Among the movies, there is an experimental film made by the deranged filmmaker Lanyard Gates, who killed many people from the audience during its exhibition. Maggie has frequent nightmares with a girl named Sara, and her mother Suzanne is not able to explain, and the film disturbs her. During the marathon, Maggie sees her crush Mark with the easy Joy and she becomes upset. Meanwhile, a serial-killer master in disguise kills Mr. Davis and several students. Who might be the killer?
