Director Michael Zen has a knack for combining the absurd, and at times grotesque, with the beautifully erotic and exciting. In this film he shows Steven St. Croix steadily lose his mind as his wife and his lover(Jeanna Fine and Jill Kelly) suddenly exchange personalities. Although some scenes are too bright for their own good, the film is very well done, owing much to the total lack of any subtlety. Zen includes trivial, but disgusting things like closeups of St. Croix rubbing greasy chicken all over his face, bringing the sex to a primal and intuitive level. The contrasts between blissful orgasms and these stoneage carnalities are incredibly effective, and I dare anyone to stay unaffected through e.g. the incredible Jeanna Fine's otherworldly masturbation scene as she tries to reach out to her ice-cold husband.
