Summer Belongs To You, Nerds of a Feather

Phineas and Ferb and their friends travel around the world. However, for once, not everybody believes they can achieve what they set out to do. Also, Candace and Jeremy's relationship will be further explored.
Phineas and Ferb head to the Tri-State area’s annual sci-fi/comic book convention to meet their hero, special effects guru Clive Addison. Their plan gets sidetracked when they’re swept into a duel between fantasy fans and sci-fi geeks. Meanwhile, Candace tries to keep secret that she’s a fan of Ducky Mo-Mo, another convention staple. Across the convention hall, Dr. Doofenshmirtz has taken television executive Jeff McGarland hostage so he can pitch him a show he’s developed, Doof ‘N’ Puss.
