Master of horror John Carpenter returns to form -- and to the director's chair -- for this chilling thriller in which a young woman, Kristen (Amber Heard), is sent to a mental institution with a past as dark and haunted as her own. Terrorized by a ghost, each of the other patients in Kristen's ward begin to disappear, and that's just the beginning of her long nightmare. Jared Harris ("Mad Men") and Danielle Panabaker (Friday the 13th) also star.
