Darren Mullet (Calvin Dean) doesn't have it easy. He's overweight, uses an inhaler and is constantly bullied by his spoiled classmates. His suicide prompts Bradley (Alex Pettyfer), Darren's main tormentor, to host a wild party, where Justine (Tuppence Middleton) hooks up with Alexis (Dimitri Leonidas). With her entry into the school's popular group cemented, Justine figures life will be easy. But when Bradley and Alexis's friends start turning up dead, everyone starts to panic.
