Alyssa Hale is a teenager with a dual personality. Normally a quiet young lady with a gloomy personality, Alyssa has a dark side, a cruel and merciless man known as Mr. Bates who can possess her body at will. Alyssa's only protection against these unwelcome possessions is an amulet given to her by her father, the director of a major San Francisco hospital. Alyssa has just undergone extensive psychotherapy and is recuperating by visiting a lifelong friend of her father's, Philip Tate, and his children. Unbeknownst to Alyssa, Philip's family is haunted by the Maxwell Curse: a mysterious figure who loves to wear a devil's mask and slaughter his victims with a large butcher knife. This is the beginning of a nightmare journey.
