Assisted by Sean, Whitman goes hunting in the hills for witches. His armed posse breaks up what is apparently meant to be a witches' Black Sabbath. He kills several of them and tells the rest to scatter to the hills and never return. This angers the leader of the coven, Oona. To get revenge on the Whitman family, Oona summons a demonic spirit to destroy the family. Unfortunately, the spirit takes possession of the loyal servant, Roderick, who Maureen Whitman has been in love with for years. Roderick begins to systematically kill off members of the Whitman family, including Sean and Lady Patricia.
