The film opens with Mäddy Killian (Caitlin Stasey) recording footage of her childhood friend Alexis (Felisha Cooper) as she prepares for the final days of school before summer break and for cheerleading practice. She discusses how important it is to remain fit and how dangerous cheerleading can be, pointing out how easy it is for some of the more advanced cheerleader moves to end with severe or deadly injuries. This proves to be the case when Alexis is thrown into the air and her teammates fail to catch her in time, resulting in her death.
