When mysterious and frightening things begin happening to Alex Wilson, she assumes that the perpetrator is the ex-husband with whom she'd been fighting for custody of their 7 year old son, Danny. Fearing for their safety, she approaches the police for help. Meanwhile, her successful work in the publishing business has brought her a new friend, Michael (Christian Campbell), a handsome young colleague. By the time the police discover that her ex-husband has an ironclad alibi for the attacks on her, she discovers that Michael has a romantic interest in her. She attempts to dissuade him only to realize his interest is obsessive. Driven mad by her failure to share his passion, he attempts a murder-suicide. She survives. He does not. But her relief is short-lived when he returns from the grave to take her back.
