Dan Gillis (James Farentino) is the sheriff at the small town of Potter's Bluff, which suddenly seems to have an epidemic of homicide. Mutilated corpses are turning up, and we see that the perpetrators are gangs of ordinary citizens attacking outsiders. Dan, however, is even more perplexed than the audience, especially when one of the victims turns up alive with a new identity. Dan's paranoia increases when he suspects that the town's old mortician, Dobbs (Jack Albertson), who is also the medical examiner, may know more than he's saying, and when he finds that his wife, Janet (Melody Anderson), has been reading a book on witchcraft. Then he gets a piece of film that reveals the true horror of the situation, and one especially shocking revelation ...
Verdict: Very creepy picture with a disquieting premise. ***.
