The Quiet Ones - John Pogue

In 1974, in Oxford, Professor Joseph Coupland invites his introspective student Brian McNeil to film his research about the supernatural with his two assistants, Krissi Dalton and Harry Abrams, and the subject Jane Harper. Jane is a young woman with no memory from the past that has been abandoned that believes she is possessed by a doll named Evey that gives telekinetic power to her. She is kept awake in an isolated house with a doll, where Prof. Coupland intends that she puts her evil energy in and then destroy the doll to healing Jane. Strange things happen in the house and Brian feels sorry for Jane and he researches her tattoo, learning an evil secret about the past of Jane.
