Locked in the cloakroom after school as a Halloween prank, Frankie (Lukas Haas) meets the ghost of a young neighborhood girl, Melissa Anne Montgomery (Joelle Jacobi), who had been found strangled to death 10 years before. Frankie soon learns that nine other children have been killed in the years since, and with the spectral help of Melissa and her mother, a grieving apparition known as The Lady in White (Karen Powell), he attempts to discover the murderer before he becomes his latest victim.
