In this film, American Professor Dana Andrews investigates a devil-worshipping cult active in England. The cult has apparently been responsible for more than one death in recent months. When Andrews comes too close to the cult for comfort, the devil-worshipping leader slips a cursed parchment into Andrews' research files. This 1958 American release is a re-edit of Tourneur's original 1957 British film.
