Welcome to Seabrook, a suburban town preoccupied with uniformity, traditions and pep rallies. That is until one groundbreaking semester when students from Zombietown integrate into Seabrook High School! As the human and zombie students struggle to coexist, a budding friendship between a cheerleader named Addison (Meg Donnelly) and a zombie named Zed (Milo Manheim) could unite their high school and community for good. Zed and Addison are back at Seabrook High, where, after a groundbreaking semester, they continue to steer both their school and community toward unity! But the arrival of a new group of outsiders – mysterious werewolves – threatens to shake up the newfound peace and causes a rift in Zed and Addison's budding romance! It's Zed and Addison's final year at school, and Seabrook has become a haven for monsters and humans. Zed is trying to get a football scholarship to be the first Zombie to attend college, and Addison is organizing an International Cheer-Off. When intergalactic outsiders show up to compete in the Cheer-Off, Seabrook grows suspicious that they may be looking for more than a friendly competition.
