A wink at the monster movie genre with zombies as the heroes, the story is set in the fictitious world of Seabrook, a cookie-cutter community brimming with perky conformity 50 years after a zombie apocalypse. Today, though the zombies pose no threat, they are still required to live in Zombietown – an isolated, rundown community that has been infused with their unique creative spirit. When it is announced that zombies will finally be allowed to enroll in Seabrook High School, life will be forever changed.
“ZOMBIES 2” picks up a few months after the original in the town of Seabrook, where the newly united communities of humans and zombies are reveling in their new-found peace. Addison is finishing up an exciting and competitive session at cheer camp and Zed is preoccupied with his plan to ask her to Prawn, Seabrook High’s mighty shrimp-themed prom. However, when a new group of mysterious teenage werewolves unexpectedly arrive in search of an ancient life source buried somewhere in Seabrook, a fearful city council immediately reenacts Seabrook’s anti-monster laws, making it impossible for Zed and Addison to attend Prawn together. Determined to keep their plan to be the first zombie/cheerleader couple to go to the prom, Zed runs for school president against cheer captain, Bucky, in order to change the rules.
It’s Zed and Addison’s final year at Seabrook and things are better than ever. The town has finally accepted monsters as a part of Seabrook and has become a safe haven for monsters and humans alike. Zed is on the cusp of receiving a football scholarship and becoming the first Zombie to ever attend college (and he’s excited to join Addison who has already been admitted). Addison is excited to mark the opening of the town’s brand new “cheer pavilion” by inviting cheer teams from all over the world to compete in an “international cheer-off.” However, the town is shocked by the arrival of a new group of intergalactic outsiders — Aliens, who show up to compete in the cheer-off. Though they begrudgingly allow the Aliens to stay for the competition, the monsters and humans of Seabrook grow suspicious when they discover that the Aliens may be looking for more than a friendly competition.
