The movie starts with a football player named Jackson Pace walking into his residence. He sets an alarm for the evening and takes a nap, only to wake up to discover that his phone is missing. The front door was unlocked, and he could sense that someone had snuck into his home. When he begins to call 911, he discovers that his photographs have been glued to the walls of the house. These photos were taken on the night when Jackson had beaten another student at his school, Caleb, as part of a haze, who ended up having a fractured jaw and other serious injuries. Jackson enters his closet area and tries to find the intruder, before the a figure reaches out from under a clothes rack and uses a long knife to slash the back of his ankles. Jackson discovers that the intruder is wearing a mask resembling Jackson’s own face, before the masked man kills him by stabbing him in the shoulder. The man then exposes the film of Caleb’s assault to the entire school.
