Molly (Haley Bennett), a 17-year-old girl, was stabbed by her mother and survived. Although she has healed from the wound itself, she is still haunted psychologically by the experience. Her father, who she goes to live with, moves her to a new school to help cope with the trauma and start a new life. However, as her eighteenth birthday approaches, Molly must both deal with the stress of being a new student at her school and the continuing nightmares she has of her mother's attack on her. Symptoms of psychosis that seem to be affecting her seem to foreshadow an onset of the mental illness that took control of her mother's life, but the truth is revealed as the most unforeseen and terrifying possibility of all. Ultimately, Molly discovers that her mother and others who share her mother's concerns want her killed in order to save her from a preordained life as a servant of the Devil. She discovers that her parents made a pact with the Devil to save her life. Molly stabs herself trying to break the pact that her parents made with the devil, but the clock had already struck midnight making it too late. In the closing of the film, Molly's father is locked up in the psychotic ward, and she has become a servant of the devil as well.
