Here’s a twist on the zombie genre we haven’t seen before. In the horror comedy flick Cooties, only those who haven’t been hit by puberty can be infected by the zombie virus, forcing the teachers of this school to take a stand against their once-adorable students. Prep your cootie shot and watch the first trailer here.

Cooties premieres in theaters and on VOD on September 18th. Read the official synopsis to earn a gold star for the day:

From the twisted minds of Leigh Whannell (co-creator of Saw and Insidious) and Ian Brennan (co-creator of “Glee”), COOTIES is a horror comedy with unexpected laughs and unapologetic thrills. When a cafeteria food virus turns elementary school children into killer zombies, a group of misfit teachers must band together to escape the playground carnage. The film stars Elijah Wood (The Hobbit, Lord of the Rings), Rainn Wilson (“The Office”), and Alison Pill (“The Newsroom”) as teachers who fight to survive the mayhem while hilariously bickering in an uncomfortable love triangle on the worst Monday of their lives.

Remember, it’s circle circle dot dot, folks — that’s how you administer a cootie shot.
