Major Briggs has no memory of the place he was taken, but now has an odd tattoo on his neck.  Andy and Dick break into Little Nicky's files.  Mike and Nadine begin an affair.  Shelly and Bobby's love is strained.  Evelyn asks James to kill her husband.  Hank attacks Big Ed, but is beaten by Nadine.  Ben slips deeper into his fantasy life.  When the drug bust goes bad, Cooper is taken hostage by Jean Renault.  Leo Johnson comes back to life.  After physical and mental torture by Renault, Cooper is saved by a quick thinking Bryson and Truman.
Later that night, an explosion and blackout empties out the police station, and when Cooper and Truman return, they find a gruesome scene let by Windom Earle.
