First, Rosemary's Baby. Then, The Exorcist. And now a motion picture that probes further into the mysteries of the occult! A heretic priest (Christopher Lee) plots to use a teenage nun (Nastassja Kinski) in a depraved pact with the forces of darkness. But when an American occult novelist (Richard Widmark) uncovers the conspiracy, he must battle an international cabal of evil for the body and soul of the Devil's child-bride! Honor Blackman and Denholm Elliott co-star in this notorious shocker directed by Peter Sykes (Demons Of The Mind) and based on the best-selling novel by Dennis Wheatley (The Devil Rides Out).
