From the award winning writer of Buried and a producer of THE CONJURING comes an incredibly chilling story based on the events of Autumn 1976 when a small psychology lab became the unwitting home of the only ever U.S. government confirmed case of possession. In what quickly became a matter of national security, leading paranormal psychologist Dr Henry West discovered that his latest patient Judith Winstead had inexplicable powers that simply could not be controlled. After being classified for nearly forty years, this is the frightening story of the Atticus Institute.
