Lucky McKee and Chris Sivertson direct this US comedy horror in which a rebellious girl enlists as a cheerleader with unexpected results. Maddy (Caitlin Stasey)'s instinctive dislike of cheerleading is consolidated when her friend Alexis (Felisha Cooper) dies during a cheerleading exercise. However, she feels compelled to become a cheerleader herself in order to teach a lesson to Alexis' ex-boyfriend Terry (Tom Williamson), who has already begun dating another cheerleader. Events take a startling turn when a fatal car crash and an ancient ritual add a supernatural element to Maddy's plot. Will anyone be able to stop the cheerleaders taking their revenge?
