Plot

In 1974, a student attends the class of Oxford University’s Professor Joseph Coupland, who wishes to prove that the supernatural does not exist. Coupland shows a video of a possessed boy and explains that research will be done to find a cure for this kind of disorder. One of his students, Brian McNeil, is invited to film the experiment process and joins Coupland, his two assistants Krissi Dalton and Harry Abrams, and their subject Jane Harper, a young woman who generates strange phenomena and has been abandoned. Jane is generally kept locked in a room with loud rock music playing during the daytime to prevent her from sleeping in the hopes that the regimen of sleep deprivation will result in increased activity.
