Watch The Quiet Ones

The Quiet Ones is a 2014 British Horror film that takes place in the 1970s in Oxford. Brian McNeil, a college student, decides to attend the class of a college professor trying to prove that there is no such thing as a supernatural phenomenon. In attempts to prove his theory, he shows a video of a young boy obsessively drawing a portrait of a man that is seemingly possessed by a demon.

Coupland's theory is that every supernatural phenomenon such as possessions and ghost are an actual cause of an unstable mental illness from some form of negative energy. He then explains that more research needs to be done to allow the finding of a cure for the disease, and that if it could heal one person than it would be able to heal the entire human race of the supernatural occurrences. Brian volunteers to be part of Coupland's experiment unknowing the trouble that awaits him and everybody that volunteered to be a part of the project.
