It is like paranormal witness except the premise is that of a series of allegedly factual surveillance videos documenting the downward spiral and eventual supernatural rape and murder of a woman named Samantha Finley.The film opens with a notice, revealing that a young man named Thomas was convicted of raping and killing his sister, and murdering Dr. Edgar Lauren, a psychic. He was sent to prison, where he committed suicide. Samantha Finley, her older brother Thomas, and their mother Ellen, believe that Ellen has been making contact with her deceased husband. Soon the family claims that a demon is haunting them. At first, they think it is David, but after a series of horrible attacks on Samantha, they suspect otherwise. I hope this helps you :)
