When a meteor crashes into Colepepper Zoo, a virus that transforms the animals into slobbering zombie-like mutants is unleashed. Gracie, a young quirky wolf, teams up with a gruff mountain lion named Dan to find a way back to her pack. As the zoo is overrun, they must come up with a plan to get all the animals back to normal. Together with the help of a motley crew of survivors - Xavier, the movie-obsessed lemur, Frida the fiery capybara, Ash the sarcastic, fabulous ostrich and Felix the treacherous monkey - they embark on a perilous mission to rescue the zoo and defeat Bunny Zero, the deranged mutant-king determined to spread the virus beyond the zoo walls. Welcome to... THE ZOOPOCALYPSE!
