Your baby is almost due,
so come right over once the contractions begin.
Got it.
It's been a month since Han Seo Joon's arrest,
but the police have yet to find the heads of his victims...
other than the couple at the campsite...
which is only hindering the investigation.
Han Seo Joon, the notorious serial killer...
known as Head Hunter who beheaded at least 20 people.
He still remains silent though...
as if to taunt the police...
which the authorities...
Hey, what are you doing?
- What are you doing to this boy? - Get off me!
- What are you doing? - Ma'am, you can't do this.
- Get off him. - No!
- No! - Get off him.
- No, you can't! - Gosh.
No...
You got your baby tested, didn't you?
What do you plan to do?
Don't have this baby.
You must not have this baby.
Never. Don't have this baby.
- What are you doing? Let go! - Don't have the baby!
- My gosh. - You must not have this baby. No!
No!
She tried to commit murder-suicide.
Poor kid. Why try to take the kid with her?
The numbers are around 30 to 40.
We'll keep him on watch.

The suspect in the tie knot murders...
died after being attacked by an acquaintance...
while being treated at the hospital.
Since there's no right of arraignment,
the case will be closed.
What the...
- Are you all right? - What?
Right.
What's with your hand? Did you injure yourself?
No, it got jammed between a door.
Anyway, come out when you're done.
Did you make all this?
Yes.
We could've just eaten out.
It's fine.
I'll enjoy it then.
It's not much.
It's good.
So about yesterday...
Did we perhaps argue?
I remember coming here, but my memory ends there.
You grabbed me by the collar the moment you came by...
and swung at me.
I had to subdue you. I'm sorry.
No, don't apologize. I'm the one who's sorry.
I really should cut back on my drinking.
You should or it could someday kill you.
I won't die.
Not until I kill the scumbag.
I understand your wrath,
but Han Seo Joon's already on death row.
What good does that do...
when he's still alive eating his meals every day?
The nation won't execute him, so I should do it instead.
Talk about having the worst luck ever.
The suspect I chased for a year jumped from a building...
and I was only suspended for a year even though I killed a man.
Then, someone beat me to killing another suspect.
Can my luck be any worse?
It's the other way around. Father Ko is looking out for you.
I've been remembering the events that happened before my injury.
The Father Ko I remember...
always worried about his little brother.
It hurt him to feel your pain.
Don't get water on that hand. You don't want an infection.
- Hey, Bong Yi. - How's your hand?
Is it all right?
Yes, it's fine.
No, don't kill him. Don't kill him.
Smash that into his face. Kill him!
Kill him. Smash his head.
Kill him. No!
- Ba Reum? - Bong Yi.
Your hand. What happened?
Oh, I... I...
It got trapped in a doorway.
Anyway, Detective Ko was absolutely wasted.
I was helping him inside when he fell down...
You idiot! You should've gone to see a doctor.
Let's go.
Remember what the doctor said.
You should be careful while the bones get set in place.
Got it.
A nasty brain has been placed in this mouse.
It might kill you too if you let it live.
A nasty brain...
might kill me from within?
I'm baffled at how quiet it's been.
The world should've been shaken right about now.
The world's first successful brain implant.
Inside Jung Ba Reum's head...
lives the brain of a serial killer.
Have you decided to keep your mouth shut instead?
Well, I'm disappointed.
I thought this would finally make me as famous as Daniel Lee.
There seems...
to be a problem.
I almost killed a man.
What on earth...
is happening to me?
Tell me.
I once transplanted...
the frontal lobe of a violent mouse into a docile one.
The mouse that used to be docile...
slowly started to become violent.
And in the end...
Are you scared...
that the same thing might happen to you too?
I'm also quite curious myself.
You were the first human to get a frontal lobe transplant.
But of course, I didn't replace your entire frontal lobe.
It was only the parts that got damaged.
But I hope that you won't let Yo Han...
take over you.
I really mean it.
Detective Ko, I'm sorry.
I must've been...
Did you hear the results?
She turned out to be Jung Man Ho's daughter.
It wasn't Hyun Soo.
Then...
Then what about my daughter? Where is she?
Sir.
Sir!
I'm getting a lot of visitors today.
It's nice to receive special treatment here.
They even let me have two visitors a day.
Why didn't you tell me?
Why didn't you tell me that the remains wasn't my daughter?
I never said it was her.
Where is she?
Where did you bury her? No...
Where did you abandon her?
I'm not sure.
It was so long ago that I can't seem to remember.
You don't remember? You don't remember?
My wife's time stopped ticking 25 years ago...
when you kidnapped our kids.
But you're sitting there telling me you can't remember...
because it's been so long?
Before you get angry at me,
you should blame yourself for speaking rashly.
You little...
You know what? I'm sorry.
I'm sorry, sir. I apologize.
If you want me to rip my tongue out, I will.
So please just allow me to bury my daughter...
at a decent place with sunlight.
Gosh, I really don't remember.
- You need to stop bothering me. - You jerk!
I'll kill that punk!
- Calm down. - You darn scumbag!
Tell me where my daughter is!
Get off me! Let go! Hey!
Let go of me! I'll kill that jerk!
Let go! Let go of me, you punk!
You'll end up regretting...
shooting Yo Han.
Yes.
I already regret it.
If I knew he was your son,
I would've killed him after letting him see me kill you first.
You have no idea how much I regret...
not having done that.
I don't see any signs of rejection.
Everything seems fine.
- Is there a problem? - The thing is,
I keep getting flashbacks from Sung Yo Han's memory.
And I think I've become a lot more violent.
What if I end up becoming like him?
This is why...
we didn't want to share whom the donor was.
Did you start having those symptoms...
after you found out that the transplanted brain...
used to be Sung Yo Han's?
Yes.
- But... - People who receive transplants...
sometimes believe that they've become similar to their donor.
I'm sure it's even worse for you...
since you received his brain.
I'll prescribe you some medicine. Take them regularly.
(Pyeongan Precinct)
It's like you're the first freelance constable in Korea.
I know the chief told you to take it easy,
but this is too much.
- I'll do it. - No, it's fine.
Plant some flowers outside.
We need some photos of the precinct for a PR brochure.
And the chief thinks the flower garden is too empty.
Okay.
Oh, I almost forgot. Give that to the evidence managing team first.
We left out an evidence regarding Kang Min Joo's murder.
- Oh, really? Okay. - Yes.
- I'll be right back. - Okay, see you.
Detective Ko.
Detective Park.
I'm leaving you evidence regarding Kang Min Joo's murder.
(Sung Yo Han...)
(Sung Yo Han Murder Case)
This is all just psychological.
I'll be fine.
What are you doing?
We left out a piece of evidence regarding Kang Min Joo's murder.
So I brought it for you.
But what were you doing on my computer?
I was looking for the brooch...
that belonged to Bong Yi's grandmother.
She was wearing it on the day of the incident,
but Bong Yi never got it back from the police.
Bong Yi seems to really want it back.
I looked inside the evidence box, but it wasn't there.
So I thought it might at least be on the list.
That's why I was on your computer.
- Her brooch? - Yes.
I'll look for it.
Okay. I'll be off then.
Let me know once you find it.
(Sung Yo Han Murder Case)
There's no brooch.
Here you go.
A, a former detective and suspect of the tie knot serial murders,
worked at a moving company after retirement...
while raising a son all by himself.
And he had a very good reputation among his acquaintances.
You spiteful wench.
Why in the world are you back here again?
Will you please leave this neighborhood?
If I make you feel uneasy, you should be the one to move.
You're at fault for giving birth to a son like him.
What did you just say?
Just move to another neighborhood!
Get off me!
- Detective Ko. - What's the matter with you?
I'm very interested in the Bible these days.
An eye for an eye, a tooth for a tooth.
If you ever do this again,
I won't let it slide no matter how old you are.
Where are you going, Detective Ko?
Why did you lie to me?
It's so upsetting.
Mom.
That girl...
grew up to be a pretty lady.
Let go of me!
Why are you here?
I heard you asked Officer Jung to find your grandmother's brooch.
I went to the hospital to talk to you about that,
but you were already gone.
Why couldn't you stay a few days and get some IV injections?
Do you think I have an easy life?
So did you find the brooch?
No, I couldn't find it.
It's not even on the evidence list, so she must've dropped it somewhere.
Maybe.
What are you doing?
Don't you know that Kang Duk Soo got out of prison?
I can't believe you had the guts to come back here.
Of course, I know. The entire country knows.
Do you know how close he lives from here?
He doesn't live here anymore.
His mom does.
- Who knows when he might return? - So what?
I can't always be on the run because of that.
Where do you suggest I go this time?
Should I just live on the streets?
Do you think I wanted to come back to this horrible neighborhood?
My grandma and I ran away and lived in an empty house...
that was located in a redevelopment area.
Among all the houses in Korea,
this is the only place I can live in.
This house that my dad built.
You should come to my place for now.
- Pack what you need. - No, why would I go to your place?
Who do you think you are? You're not my dad.
Well, I'm obviously not...
your dad.
Do you even eat properly? Do you eat ramyeon every day?
I eat well.
You're the one who shouldn't skip meals.
I'm leaving.
About Woo Jae Pil.
- Yes? - Did he work for a moving company?
That's what they said on the news.
Yes, he worked in a team for a moving company.
- Why? - His hand was...
way too soft for someone...
who worked for a moving company.
It felt like he never worked a hard day in his life.
He couldn't have done physical labor.
Also, when he covered my mouth with his hand,
I felt something cold. Like something metallic.
- Metallic? - A ring?
I'm not sure.
Bong Yi said his hand was soft.
But Woo Jae Pil worked at a moving company after retiring.
His hands couldn't be soft.
Can we talk later? I have to finish this today.
You saw him in person.
They used to baby you and say you were the National Son.
But now, they make you do this with an injured hand!
- Stop it. - Should I call reporters here?
Stop it. You'll make me look bad.
I feel uncomfortable around Officer Nam as is.
What? Officer Nam ordered you to do this? Not even the chief?
You should care for you sick colleague...
No, no. Please. I'm fine. I say I'm fine.
I'll do it. Sit down. I'll be quick.
I can do it faster.
Just plant those, right?
Why are they suddenly doing this?
I hate putting up pretenses like this.
Detective. Do you have the pictures?
The pictures from the scene...
where Park Hyun Soo, I mean, where Jung Soo Jin was found.
Woo Jae Pil confessed to digging the hole...
- and burying her himself, right? - Yes.
Look. I'm a righty,
so I grab the back of the handle with my right and lead with my left.
This is how I dig.
When the shove hits the ground, the left tip has all the power,
so the left side gets dug deeper than the right.
But look.
If a lefty dug it, it should be the opposite.
But it's the same as the hole I dug.
That's right. It should be the opposite...
since Woo Jae Pil was a lefty and you're a righty.
He was definitely a lefty.
So someone else dug the hole.
I see why it's in the same direction.
He has a cast.
He had to dig with his right hand because of the cast.
He couldn't have tied the knot with just one hand.
So there was another lefty who tied Jung Soo Jin's hands together.
I remember the knot in the rope around Jung Soo Jin's wrists...
- As if a child tied it. - He said it was clumsy.
A child. A child...
Woo Hyung Chul was...
12 at the time. He was in the 5th grade.
But Woo Hyung Chul had a solid alibi...
during Hong Na Ri's time of death.
That's what we have to solve now.
During Hong Na Ri's time of death,
Woo Hyung Chul was installing bars on that window.
Were you home the entire time it was being installed?
Of course. Quiet.
That's right. I took Simba to the vet for a short while.
Was Mr. Woo here when you got back?
He was finishing up.
How long were you gone?
About 20 minutes?
The vet is just on the big street.
20 minutes.
What was wrong with him?
He had a convulsion.
They said he went into shock due to hypotension.
They asked if I fed him xylitol.
All I ever fed him was dog food.
Maybe he ate something when I took him on a walk.
He fed something to the dog...
to create his alibi.
Okay. It takes exactly eight minutes by car...
to Hong Na Ri's place, so 16 minutes round trip. Next.
- Are you done? - Yes.
Next, my neck.
Here I go.
Strangle me.
That's a bit strong.
It's too strong.
More. Squeeze harder.
Harder.
It'll feel really good.
Darn it. You freak.
What's your problem?
All you had to do was pretend! Why did you squeeze so hard?
- Untie me now. Hurry. - Okay.
Untie me.
That's 20 minutes already.
It was impossible to kill her here and get back...
in time.
Are you okay?
Yes. Are you okay?
- I almost died, you punk. - I'm sorry.
I'm dizzy.
It's 16 minutes round trip to Hong Na Ri's home and back.
Tying her up and murdering her takes 5 to 10 minutes.
It takes at least 20 minutes.
She would've resisted, so if he had to suppress her...
and cleaned up, 20 minutes isn't enough.
20 minutes isn't enough.
You look terrible.
Go home and rest after you eat.
Okay.
Anyway, you've changed a lot. You keep surprising me.
- What do you mean? - To be honest,
before you hurt your head,
I didn't think this job was a fit for you.
But now,
I feel like you can read the mind...
of killers.
Yes. How could you chance so much?
Maybe I should get brain surgery too.
I haven't changed.
That's hot.
I was complimenting you.
You're so sensitive today.
I'm sorry.
I burned the roof of my mouth because of you.
- Go get me a beer. - Okay.
That punk.
Here you go.
Why isn't this beer cold?
I wanted to cool a pot of bone broth,
so I took them out for a bit since there wasn't enough room...
- and just put them back in. - What is this?
It's plenty cold. You're so finicky.
Finicky?
Beer should be drunk ice cold!
I don't want it! Put it back.
Pain in the butt.
What did you just say?
Me? I... I didn't say anything.
You said something to me.
Detective.
I found it. The solution to the Woo Hyung Chul riddle...
for the day of Hong Na Ri's murder.
Have a nice day.
It's cold. Go back in.
Hello.
How was your father's funeral?
It went well. Thank you.
What brings you here?
- You have soft hands. - Pardon?
You're relieved that your dad died and took all the blame, aren't you?
What are you talking about?
Your dad was so naive.
He probably thought if he died for you,
you'd feel guilty and get your act together.
- Look here. - But sorry.
I'm an expert on scumbags like you.
Scumbags like you can't stop killing people.
It's out of your control.
It's an addiction.
You psychopath.
Then crack my alibi during Hong Na Ri's time of death.
Before more people die as you say.
A few days ago,
I got really sick...
after drinking bad milk.
But that milk was in the fridge and hadn't expired yet.
So why did it go bad?
But the place I drank the milk was Hong Na Ri's home.
Yesterday, I tried to get a beer at a market,
and it was lukewarm.
I complained to the owner and asked why it wasn't cold,
and she had put in a pot of bone broth...
and removed the beers for a while.
When he saw that pot, our smart Officer Jung figured it out.
Something that doesn't belong in a fridge.
You did not murder Hong Na Ri that day.
You set the fridge to one degree.
The windows were sealed, so it was 27 degrees in the room.
The body would've started to decay within a day in that temperature.
But you put it in the fridge, so it didn't decay for two days.
You needed an alibi,
so you chose the home closest to Hong Na Ri's to install the bars.
You saw in the file that she had a dog.
And then you brought something poisonous for the dog.
Mr. Woo, I need to leave for a while!
Sure thing.
Once the resident left as planned,
you headed to Hong Na Ri's house.
You took her body out of the fridge...
and texted her separated husband over to the house.
Can you come home right away?
Why? To create your alibi.
Someone had to find her before the body decayed.
You then came back to finish installing the bars.
I'm sorry about that, Mr. Woo. My dog suddenly got sick.
- Is it okay now? - On that day,
you only needed five minutes to take her body out of the fridge.
Three days prior to her body being found,
on the 5th from 4pm to 6pm, you have no alibi.
You went home early at 4pm...
complaining about being under the weather.
It's only a 30-minute drive from the office to your house,
and Hong Na Ri's house is along the way.
Your car was filmed on camera an hour after you left the office.
There's a 30-minute gap...
which is the time one would need to kill Hong Na Ri...
and stage the scene.
I didn't know I was talking to the Brothers Grimm.
How about you begin a career as novelists?
It seems more up your alley.
Shall we, Officer Jung?
I'm more into documentaries than novels.
Yes, me too.
Why don't we show him this then?
The DNA sample found in the fridge...
is a 99 percent match to Hong Na Ri's. See?
Do you have a warrant for my arrest?
Then, bring that to me first.
Because of you, I'm late for work,
so excuse me.
What's taking so long?
See when we'll get our warrant.
As if I need one, you scumbag.
Are you looking for these?
What? What the...
- I emptied the gun while you slept. - Give them back.
- Give them back! - No way.
- Come on. - Not these.
- Give them back! - No way.
- Never. - What?
Stop right there. Darn it!
- Hey, you! - Detective!
You're under arrest for the murders of...
Kim Young Hee, Kang Min Joo, and Hong Na Ri.
Anything you say can and will be used against you...
- in a court of law. - How did they get here?
Isn't it obvious?
You didn't request the warrant you mentioned,
so I asked Detective Shin for one.
Darn you, Officer Jung!
Detective,
you were protected once again...
by Father Ko.
A second operation?
Yes, I want one.
The medicine you gave me isn't helping.
That'd be impossible.
Sung Yo Han had died of cardiac arrest...
and his brain was harvested before the nerves died.
There's no brain to implant this time.
I'm sure there's a way though,
so please look into it.
I'm now hearing things, you know.
Something might happen...
which terrifies me.
Even if we find a brain, you can't be operated on.
If the world finds out about this,
we'll all lose a great deal.
It's too dangerous.
Us all?
What...
You think your loss will be greater than mine?
I could lose myself as I know it.
Sung Yo Han's mind might take over mine!
If something happens to me, it'll be your fault.
So be ready to take responsibility for it.
A new suspect in the tie knot murders...
is now being investigated by the police.
He turned out to be the son of the original suspect, who is now dead,
so we look forward to...
- what the investigation unfolds. - Yes, doctor.
The police have requested a warrant for his arrest...
and the decision to re-investigate the tie knot murders...
has been decided.
This is Choi Young Shin.
I have an urgent favor to ask.
(Supermarket)
Hey, you.
Aren't you too young to have a fat tummy?
What's this?
Please look the other way just this once.
Here, take this with you.
The mom's an alcoholic.
She's been drowning herself in alcohol after the divorce.
Does she live around here?
I don't think the mom even sends her to school.
She spends all day with her mom.
After that monster was released from prison,
all the families with children moved away,
but I don't think the mom knows that he's back here.
- Who's back here? - Didn't you know?
Gosh, you really didn't.
Kang Duk Soo is back here.
I can't believe the police.
Shouldn't they have told you first?
I'll get going.
(Supermarket)
Hey, kid!
I won't take it from you.
Here.
Take this too.
The bun itself will be too dry.
What's your name?
Yu Na.
Yu Na, let me walk you home.
Come on.
Yu Na!
Yu Na.
Take this and enjoy it inside.
Go ahead.
Move out of this neighborhood.
As soon as possible.
Move?
Who are you to make demands at someone else's house?
Kang Duk Soo is back in this neighborhood.
So what?
I can look after my daughter just fine.
So move away yourself if that's what you want.
But you're...
But you're her mom.
Aren't you worried about her?
I said I can manage my daughter just fine.
Darn brat.
Who are you to meddle with our lives...
telling me to move away?
What if I told you I'm his victim?
Does that give me the right to meddle?
You're her guardian.
So keep her safe...
and stop drinking.
Ba Reum?
Ba Reum.
Bong Yi, nothing will happen to me, right?
Will I be all right?
Of course.
You'll be fine.
Nothing will happen.
Why though?
- Stop it. - Why was it dismissed?
Keep it down, will you?
Lack of evidence.
But Hong Na Ri's DNA was all over the inside of that fridge!
What can we do when we have our orders?
They want us to bring solid evidence.
I swear it's him!
The arrest warrant for the newly chosen suspect, A,
has been dismissed.
People are starting to criticize the police...
for their rash and coercive investigation...
Stop sighing. Let's find something he won't be able to deny.
- What's that? - Kim Young Hee's mother...
gave me this notepad. But there's nothing on it.
(I cooked ramyeon at night...)
This woman next to Kim Young Hee seems familiar.
Where did I see her?
Can I take this?
Do you have something to say?
No, it's nothing.
I know you, Detective Ko. What is it?
It's just a small favor.
Can you take care of someone for about a month?
- Who is it? - Just someone I know.
Don't ask any more questions.
- No. - If a month is too long,
- then how about a week? - I said no.
I wonder who it is.
He's normally not the type to ask favors.
(Ba Reum)
The receiver cannot be reached. You will be directed to voicemail.
Hey.
Thank you.
Detective Ko, are you okay? You're so quiet for someone so big.
I'm sorry. Oh, gosh.
Be gentle.
Woo Hyung Chul got released.
Be careful when you walk alone at night.
He wasn't even that strong.
You saw how good I am, right?
I guess you learned how to fight instead of studying at school.
Here.
What's this?
Who's Sung Ji Eun, and why did she send you so much money every month?
Are you a gigolo?
No, you don't have the face to be a gigolo.
What's wrong with my face?
That will be enough for you to get yourself a small studio.
You should move to my neighborhood. We can look for one together.
No.
I have no reason to receive this money from you.
Take it. I'm not giving it to you. I'm lending it to you.
- Plus, it's not my money. - No, it's not that.
Running away isn't going to solve anything.
I want to overcome it here.
Even if I run into him,
I'll make him avoid me.
Okay, fine. You really don't listen.
Instead, you'd better call me first if anything happens.
Okay?
Okay.
You're all grown up now.
By the way, about Ba Reum...
Is there something wrong?
- Why do you ask? - It just seems like...
he has something on his mind.
Yes, he doesn't seem to be in a good condition these days.
He also seems very sensitive.
Please...
don't let anything happen to me.
Please don't let me...
become a monster like Sung Yo Han.
Please.
Please protect me, My Lord.
Please.
(Do not enter, under investigation)
(Pyeongan Precinct)
Hey, Detective Shin. What's up?
I called to tell you good news.
I think you're going to get sent to the evidence managing team.
I should start calling you Detective Jung now.
Really?
I should call Detective Ko to thank him.
No, you should thank Detective Kang.
Detective Kang?
He wants you to keep Detective Ko company.
Detective Kang...
actually cares about Detective Ko the most.
Anyway, congratulations. Just a second.
Hello?
Oh, hey. A murder case?
Okay, I'll be right there.
He always claimed himself as the deity.
Did he really resurrect or what?
Hey, Officer Jung.
Sung Yo Han's MO was found at a murder scene.
- His MO? - The finger and the cross.
- I need to go now. - Detective Shin.
I'd like to go too. Send me the address.
What a lunatic. I can't believe they copied this.
I knew something like this might happen when people...
started talking about creating a fan club after Sung Yo Han died.
Look into the members and identify the victim.
Got it, sir.
It's very stable.
It's the work of a professional.
- I smell mint. - When we rolled down together,
he smelled of mint.
It's his smell.
But why am I smelling that here?
No way.
- Did you identify the victim? - Yes.
She's a 17-year-old high school freshman.
She lived with her grandfather.
- Is this it? - Yes.
Attention, everyone.
- Is everyone here? - Yes.
We're going to report today's case as an ordinary murder case.
Make sure the press doesn't think someone tried to copy Sung Yo Han.
But why?
As you all know, the entire country ended up having a trauma...
after witnessing a live murder case on TV last year.
It's finally being forgotten.
Let's not trigger their fear with news about a copycat killer.
We were ordered to keep this investigation classified.
We don't want reporters getting a whiff of it,
so watch your mouths.
Tell whoever isn't here.
- Yes, sir. - Yes, sir.
That's right. The brooch.
Detective. Did you find Granny's brooch?
It wasn't there.
She must've dropped it somewhere else.
I told Bong Yi.
Let me see the picture of Sung Yo Han's basement.
- That's out of nowhere. Why? - Please let me see it.
Darn it. Punk.
Let me.
Let's see the video the killer sent during the broadcast.
Okay.
Moo Chi. Hey.
Why are you back again?
So he was here already.
Officer Jung must have told you already.
What? What's wrong with him?
It's different.
That means it may not have been Sung Yo Han who sent this.
That means there's a chance he wasn't the killer.
Yes. I only remember hitting him, not killing him.
The person who hit him didn't necessarily kill him.
If someone else killed those people,
it means the brain transplanted in me isn't a killer's brain.
Explain. What do you mean, his signature?
Some psycho copied Sung Yo Han's MO.
I don't think it's a copycat.
I think the killer is someone else.
Look.
The basements are different.
This is not Sung Yo Han's basement.
I think you're right.
Places look different if you shift furniture around.
Look carefully. It isn't just the furniture.
You may be right.
They didn't find Bong Yi's grandmother's brooch.
Father Ko's necklace either.
Sung Yo Han had been taking the victim's belongings.
So why didn't we find Granny's brooch and Father Ko's necklace?
He has a point.
What about Dr. Daniel Lee and Han Kook?
They were never found.
Maybe he buried them with them.
- That's true, but... - If Sung Yo Han didn't do it,
why were photos of Byun Soon Young's corpse...
in his basement?
And why did he crush your head with a hammer?
Why did he try to kill you if he wasn't the killer?
Explain that, punk.
He's right.
- You have a wild imagination... - That's true,
but remember the mint scent I told you about?
The mint scent I smelled when I fought Granny's killer.
I smelled it at the crime scene.
There are countless shampoos, body washes, and stuff like that...
with a mint scent.
- But... - Hey!
Why do you hope so badly that Sung Yo Han isn't the killer?
Are you saying I shot and killed an innocent man?
Is that what you want?
- That's not it... - Get lost, punk.
You come out of nowhere...
Get lost. Go. Go back to your precinct.
- He has a point... - Go. Get lost.
Scram!
What do they take the evidence managing team for?
Darn it. He's back.
You should bring the evidence right away if there's a case.
Must I come to pick it up myself?
Where is it?
Is this it?
Yes, that's it.
Is this everything?
I hear you throwing a fit from way outside.
You're so excited to be on the evidence managing team.
(Written Opinion)
Was she burned alive?
No, he burned her after he killed her.
(Pyeongan Precinct)
- Hello. - Hey.
Pyeongan Precinct, Officer Jung Ba Reum speaking.
A suicide?
What's taking them so long?
I'll see if the ambulance is here. You stay here.
A mint scent?
If she hanged herself to commit suicide,
why did she stick her fingers in...
to stop herself from being strangled?
That means someone tied it around her neck...
and she stuck her fingers in before he pulled it.
It was murder.
And only the middle finger is stuck in the rope.
After she died,
someone pulled out all the fingers except for the middle finger.
Why? Why?
The culprit used the middle finger to swear at that cross.
It couldn't be...
There's something there.
I thought about it, and Officer Jung had a point.
That's nonsense. You impressionable Nepo.
You and your "Nepo".
I'm just saying it's worth hearing him out, that's all.
Get out. Stop distracting me.
Hi, Officer Jung.
What? You found what?
What is it?
I swear it's true.
I saw Father Ko's cross necklace...
and Bong Yi's grandma's brooch.
But by the time I brought Officer Nam,
they disappeared.
I was surprised when he told me and ran in...
but they weren't here.
So, the only person who saw the necklace and the brooch...
- was Office Jung. - Yes.
And you hit your head when you fell off the chair.
I saw them before I hit my head.
Detective, I'm sure the killer took them.
So what you're saying is, the killer set it up and took it back.
Why?
Maybe you're too obsessed with the theory that Sung Yo Han...
wasn't actually the killer.
I swear they were here.
Check the CCTVs.
You must be getting some fun on the side though.
Check the camera by the entrance.
I did, but it was a dummy.
I swear they were here. They were.
Are you sure it was murder?
What about her identity?
- An illegal adult massage parlor? - Captain.
Please put a tail on Woo Hyung Chul.
What was that? Don't you do anything legal?
- No. - So... The thing is...
Someone else is the killer.
Good. I'll catch him myself and prove that my new brain...
belonged to a normal person, not a murderer.
(Police)
From the alley to here, it took...
three minutes.
And he waited here and dragged her away.
So he knew Kim Jin Ah would come this way.
So it's someone who knew where she lived.
Perhaps someone who had stalked her for a while...
or had been to her place at least once.
- Hello, Detective. - Hey. Where are you?
You're not at your desk.
I came out to look into something.
What is it?
I need to tell you something.
Let's talk in person. Hurry back.
What is this? Does he have OCD or something?
This makes me uncomfortable.
I can't look at things like this.
He's working hard to prove Sung Yo Han's innocence.
They were close.
She got along very well with her daughter.
She was close to Soon Young.
It's her.
Yes. When Young Hee quit,
she recommended Hye Won to replace her.
Where's Park Hye Won now?
She quit almost a year ago.
She had a really hard time after what happened to Soon Young,
- and said she was getting married. - Married?
To whom?
I think she said he was a lawyer.
A lawyer.
She texted me about a year ago that she was suddenly moving out.
She said she was moving abroad and asked me to get rid of her things.
She didn't come back for her deposit,
so I called her several times, but I couldn't reach her.
She was in school and argued about every last penny.
I got a text from Hye Won...
that she was moving abroad...
and wouldn't be in touch for a while.
Around when was that?
Almost a year, I think.
Hold on.
Yes, that's right.
But it was odd.
She isn't usually so perfect with her spelling.
It looked like it was from a stranger.
What? There's no record of her leaving the country?
Got it.
This jerk...
He killed Park Hye Won too.
How did Woo Hyung Chul know that she worked at that bar?
Check this out.
This is Woo Hyung Chul from when he was on the news.
I think it'll be best to gather all your opinions...
and then deliver them as a collective statement.
I knew it.
If she had actually struggled to free herself,
there wouldn't just be one clean rope burn...
on the dusty railing.
That means she was hanged postmortem...
and her fingers...
were staged to make it look like a suicide.
The cause of death is strangulation after all.
How did I miss that?
Detective Shin, has Kim Jin Ah's autopsy been completed?
She was Woo Hyung Chul's fiancee?
She was an orphan, so no one knew she was missing.
Everyone believed that she went abroad.
Why did he kill Park Hye Won though?
When Woo Hyung Chul was hired as Sung Yo Han's attorney,
he saw Park Hye Won who testified as Byun Soon Young's acquaintance.
It's when he found out that she worked at the same bar.
What about Kim Young Hee then?
Did he kill her because she's Park Hye Won's friend?
Kim Young Hee worked at the bar first.
She recommended Park Hye Won after quitting.
- That's why he killed her. - Why though?
He's punishing women who doesn't fit his standard...
of the women he views as ladylike.
He saw Kang Min Joo as a gold digger...
after seeing her go into a motel with a man.
He then saw Hong Na Ri with another man...
when she was still legally married to her husband.
Why did he go after Oh Bong Yi then?
He briefly represented Kang Duk Soo...
before another lawyer took over,
so of course he has all the files relating to that case.
Oh Bong Yi was Kang Duk Soo's victim.
It doesn't fit the criteria in which...
Woo Hyung Chul selects his victims.
Why weren't the bodies of...
Park Hye Won and Kim Young Hee on display?
Because he lacked confidence at first.
Once the confidence built inside of him,
he started putting his victims on display.
The missing bodies of Park Hye Won and Kim Young Hee must be found.
Or at least the murder weapon.
That's the only way to prove this man's crimes.
We'll start with Woo Hyung Chul's...
Yes, it's me.
I'll head home first.
("Police Coercion Evident in the Tie Knot Murders Investigation")
- Could I have the prescription? - Sure.
- Here you go. - Thank you.
Let's go.
Mr. Woo,
- you may enter. - Sure.
It was rough, wasn't it?
Leave it to the police to badger an innocent person.
Here's the iron supplement you requested.
It wasn't easy to get this.
How's your wife's morning sickness?
Well, she's doing better.
Wasn't that Choi Hong Ju, the TV producer?
Yes, it was.
Really? I didn't know she was married.
A rumor surfaced after Sung Yo Han's death...
about her being in a relationship with him.
It was me who tipped off the reporter.
I heard it myself while having drinks.
There are tons of other guys in this world.
But why him of all people?
Is that so?
Wait. You found traces of acetone?
Acetone is a chemical that evaporates rapidly...
and it can start a fire even with a small spark.
It's not dangerous like hydrochloric acid...
which is why it's easy to purchase in bulk.
Isn't the cause of death strangulation?
No. If the victim was strangled in any way,
the hyoid bone or the cartilage would've been fractured,
but that wasn't the case.
Nothing might've been fractured if she was strangled...
with an object that's wide like a towel.
Could you perhaps check for a congestion?
Officer Jung, that con...
- A congestion? - Yes. What is it?
Oh, that. When one is strangled,
pressure is applied on the jugular vein.
It stops blood from being pumped to the heart...
which is why one's face turns red.
The external carotid artery in the face and skull...
brings on a congestion in the face.
The congestion in the face leads to one in the skull...
which then leads to one in the centrum.
That congestion is direct evidence of strangulation.
You must've graduated med school.
No, I never went to college.
What? Then how do you know all this?
You just spoke in medical jargon.
Well...
I just happened to know them.
Just like that?
You must be a smart one.
Because Sung Yo Han was a doctor.
Does it mean I killed...
an innocent man?
Woo Jae Pil was probably aware...
of his son's crimes.
Hyung Chul...
Why did he kill my Soo Jin?
Is there anything you can tell me about Woo Hyung Chul...
that could help us?
Hyung Chul's mom tried to kill him and then commit suicide.
Ambulances came wailing for them.
How did she end up getting involved with a killer?
That reminds me. A few days before the incident,
Chang Soo drove Hyung Chul's mom to Guryeong.
Chang Soo?
Hyung Chul's uncle. He lived in the same neighborhood.
He probably still lives there.
(Laboratory Medicine)
- Officer Jung. - Yes?
You were right.
Although faint, I spotted a congestion in the centrum.
It's as you assumed. Someone strangled the victim.
Due to the ash found in her bronchial tubes,
I ruled strangulation out.
I would've missed it completely had it not been for you.
No way, Officer Jung.
I'm amazed.
It was heavily snowing that day.
I took her to a hotel...
and waited in the car.
Darn, it's cold.
She met someone in the hotel lobby.
It seemed like she was pleading.
My sister was swept with anxiety ever since she got back,
but then she asked me to take her to Seoul again,
so I did.
To the same hotel?
No, it was some research institute.
Anyway, after that trip, it was as if her mind went blank.
She almost killed Hyung Chul and then herself...
only to jump from the hospital building later on.
What's with those flowers?
Hydrangeas.
My sister loved purple hydrangeas.
Hyung Chul, being the sweet kid he is,
would visit his mother's grave from time to time.
I see...
that not all are purple. Some are blue.
To get purple hydrangeas,
lime must be sprinkled on the soil.
There must have not been enough.
Blue hydrangeas indicate acidification.
Hold on a second. Acidification?
Doesn't that happen when there's too much iron?
That's right.
What are you doing? Stop!
No, stop. You're ruining the flowers!
Step aside.
Iron is metal which means there could be a murder weapon.
Excuse me.
I'm with the police.
Did your granddaughter ever run away from home?
Jin Ah ran away about a year ago...
and hung out with other runaway boys...
which broke my heart.
She only got back recently...
and was getting her life straight.
Sir, did your granddaughter...
come back home...
after receiving consultation and help...
from someone?
Of course! That wonderful man...
made her see straight and come home.
I see.
Is that wonderful man...
perhaps him?
Yes, that's him!
(Safety for Women)
- Please call me anytime. - Who was that earlier?
He offers free consulting for runaway teenagers at times.
He convinced a lot of them to go back home.
Where's Woo Hyung Chul?
Darn it.
I lost him. There was an accident.
I told you to always keep your eyes on him!
Put him on the wanted criminal list right now.
And track his cell phone and car.
Runaway teenagers and hookers.
He killed women whom he thought were vulgar...
in his standards.
Who's his next target?
Why couldn't I reach you all day?
Dong Koo.
I sent you the script for my wedding tomorrow,
but you didn't even check it.
I called you to give you your suit, but you never picked up.
Oh, right. It's your wedding tomorrow.
You forgot about my wedding tomorrow?
Do you have a death wish? Seriously?
Open the door. Go on.
("Famous Producer Turns Out To Have Dated the Infamous Serial Killer")
I bought this for you because you told me you don't have a suit.
You darn punk. I can't believe you forgot about my wedding.
- I'm sorry. - Let me see.
Gosh, you look totally different now that you're in a suit.
Gosh, you look great in a suit.
- Look. - Why are you taking a photo?
Stand still.
Okay.
Why isn't Seul Ki checking my texts?
She hasn't been answering my calls either.
Dong Koo, I'm telling you. It's not too late.
You really should reconsider marrying Seul Ki.
I swear she'll always desire to be successful as an actor.
Where does Seul Ki live? You need to tell me now.
Hong Ju! Hong Ju!
Hey, what brings you here?
Dong Koo got into a fight with his friend from school.
He's at the police station right now.
Why... Why?
Is he badly hurt? Where is he right now?
If you let me in, I'll explain to you.
- Oh, okay. - Okay.
Come in.
What's up?
Thank goodness.
I just thought...
Seul Ki! Seul Ki, are you inside?
Call 911 and bring a cutting plier from the security office.
Hurry.
You're up.
I was supposed to kill that brat.
But you ruined it all.
I need to keep talking to him.
He won't kill me as long he's still talking.
You killed everyone, didn't you?
Yes. I killed them all.
Why did you kill them?
Tell me the reason.
"The reason"?
It's simple.
I got rid of...
all the vulgar women.
- Did you have fun today? - Yes.
You have such a beautiful smile.
I'd love to have a beautiful daughter like you, Soo Jin.
Don't buy something too sweet.
- Okay. - Come over often.
- Thank you. - Sure.
Soo Jin!
Dad!
Hyung Chul, I'm busy right now. I'll call you later.
Dad!
I think... I think Soo Jin is dead.
"The Boy Scouts taught me..."
"how to do a rescue knot."
"I was just trying it out on her, but I think I made a mistake."
"What should I do?"
I shedded a few tears, and he totally bought it.
Pull my left hand slightly to the right.
Then put my right hand on top.
My acting must've been pretty good.
Your father wanted to believe that it was a mistake.
Honey, I have a feeling...
that Hyung Chul might've...
What? What are you thinking? He said it was an accident!
What's going through your mind?
(The parents of these missing kids are desperately waiting for a call.)
The entire country was focused on the Head Hunter case.
Your father had a great idea.
He put her in the same clothes and shoes as Park Hyun Soo.
As the detective on point,
it couldn't have been hard to get her DNA.
He made it look like she was Park Hyun Soo...
in case she was ever found.
No, no.
It wasn't Dad's idea, it was mine.
- It was my idea. - You killed your mom too, right?
She brought my hair to the now dead and gone Dr. Daniel Lee.
That jerk told her...
that I was a psychopath.
Why did you kill Soo Jin?
Because she looks like you.
She has dimples like you...
and has short pinkies like you.
She's your daughter, right?
You cheated with her dad and had her, didn't you?
What?
Am I wrong?
Fine, then.
Don't worry. I'll go with you.
No.
That wench Park Hye Won was just like my mom.
But she had the nerve to want to marry me?
That's why I killed them. Those lustful and wicked skanks.
I judged them for the deity.
What about the others?
Who?
Oh Bong Yi?
Don't you know why?
You low life. Are you kidding me?
What gibberish is that?
You scumbag.
Song Soo Ho. Kim Sung Gyu. Byun Soon Young.
Jo Mi Jung. Bong Yi's grandma. Why did you kill them? Why?
What are you talking about?
Sung Yo Han killed them.
Don't lie to me. You killed them.
Sung Yo Han took the fall for you and died just like your dad.
You made it look like he killed them to cover up your crimes.
Like someone else killed them. Right?
What are you talking about?
I heard you got brain surgery.
You've gone completely insane.
Don't lie to me! You did it all.
You put Father Ko's cross necklace and Granny's brooch there!
Right?
You crazy jerk.
It really was Sung Yo Han.
It was him.
Here...
Kill him. Kill him.
You should kill someone like him.
That's it.
More. More. More!
Oh no. I think he died.
How does it feel?
You.
Isn't it exhilarating...
to kill a person?
