It's summer time and Pelle is enjoying life with his girlfriend, Ida. Crime in Middellund is at an all-time low, and life is actually pretty sweet. But Pelle has started to tire of being Antboy, and perhaps the town doesn't even need a superhero anymore?

Suddenly strange things start happening. A new superhero appears and completely humiliates Antboy; Gæmelkrå is released from Dragensborg and apparently starts working for ExoFarm again; Wilhelm completely detaches himself from the world of comic books, and eventually also from Pelle.

Pelle is forced to take matters into his own hands – he has to find out who this new superhero is; what Gæmelkrå is plotting in ExoFarm's labs; and what is going on with Wilhelm. Pelle's summer vacation suddenly takes and unexpected turn, and Pelle will face his biggest and perhaps final battle as Antboy.
