Christopher Lee stars in this weak occult melodrama as Father Michael Rayner, an excommunicated priest who decides to save the world from its decadence by teaming up with Satan. Richard Widmark is on hand as John Verney, out to stop Rayner's satanic rituals and helped along on the path of goodness by friends Anna Fountain (Honor Blackman) and David (Anthony Valentine). The plot centers on distraught father Henry Beddows (Denholm Elliott), who has signed over his daughter Catherine (Nastassja Kinski) to Rayner in order to save his own skin and now regrets it. ~ Paul Brenner, All Movie Guide
