Cry of the Banshee

The puritanical magistrate Edward Whitman puts the followers of the witch Oona to the death, although deliberately spares her. She swears vengeance for this and calls up a manifestation of the Devil in the guise of the young, handsome Roderick. Roderick charms his way into Whitman’s family and starts killing them off, as though to all appearances by a wild animal.
