Alan (Rupert Frazer), a wealthy English antique ceramics dealer, becomes smitten with a German secretary named Karin (Meg Tilly) during a business trip in Copenhagen, proposes to her, and marries her after she joins him in England. Although they’re passionately in love, a number of unsettling and seemingly supernatural eventsincluding dreams and apparent hallucinationsbegin to raise the question of Karin’s mysterious past, which continues to trouble her. Writer-director Gordon Hessler’s erotic psychological thriller, adapted from Richard Adams’s novel, isn’t an unqualified success (some choppy editing and miscalculated slow-motion occasionally interfere with the trancelike rhythms), but it shares with the memorable horror films of Val Lewton and Jacques Tourneur a preference for suggestion and understatement over explicitness, developing a gripping narrative and some disquieting and evocative moods in the process, along with some fairly steamy sex.
