When Laura unearths an old Ouija board in her closet, her roommate, Cindy, uses it and encounters the spirit of a man that had been murdered in their apartment. After Laura later witnesses Cindy being strangled to death, the authorities arrive to find Cindy missing and no evidence of a crime. Laura sets out to convince everyone that the murder was real while evading the man she feels is Cindy's killer.
