a small town in California who comes to San Francisco to broaden his sexual experiences. He is taken by a friend to a private nightclub in the City's North Beach district where he will witness the ravishment of a woman who has been kidnapped and then loved as never before.

The woman, Gloria Saunders (Marilyn Chambers) is prepared for the ultimate female fantasy by six robed women who arouse and titillate her until she is ready to accommodate an extraordinarily equipped black stud (Johnnie Keyes). He makes love to her with an exuberance and passion never seen before by the spectators who crowd the nightclub, and watch with a growing excitement of their own.

But this is still only a prelude to the ultimate experience to come. Gloria is placed among three studs on a trapeze for a bizarre climax of sexual passion. The members of the audience become so excited in the ceremony that they join in with the performers on stage. Barry, amidst all the emotion, rescues the exhausted Gloria from the club and they take off on their own, making way for the next ceremonial ravishment to occur.

Behind the Green Door has been praised by both film critics and viewers alike. Famed film critic Arthur Knight says, ". . . it is sex as ritual, sex as fantasy, sex as it could be only in the movies."
