When a mentally imbalanced prisoner (Robby Benson) gets out on parole, he tracks down the journalist (Jennifer O'Neill) who interviewed him while he was behind bars and persuades her to hire him as an assistant. But when she denies his advances, he aims for her adolescent daughter (Lydie Denier). The girl thinks she can stave off his disturbing desires -- at least for a while. But her naïveté is no match for his perversity.
