After 300 years, three sister witches are resurrected in Salem Massachusetts on Halloween night, and it us up to two teenagers, a young girl, and an immortal cat to put an end to the witches' reign of terror once and for all.

Mike Church, an L.A. gumshoe with a knack for wisecracks and tracing missing persons, doesn't have a clue when he's hired to help a beautiful amnesia victim tormented by nightmares. Then an eccentric antiques dealer and hypnotist leads Church to believe the source of the nightmares may lie in a past-life connection to Margaret Strauss, a world-famous pianist allegedly murdered by her composer husband in 1948.
