Catherine is a sensual, incredibly sexy, jaded, and traumatized high-society housewife who ventures into a depraved sexual hell through a mirror hidden in the attic of her mansion. During these "journeys" to the underworld, she inevitably encounters her deceased father (now the devil himself), who obsessively demands that Catherine enter permanently and stay with him so he can continue abusing her, just as he did when she was a teenager.

The sex scenes are intense and highly erotic, filmed with a surreal beauty and production design that offers a thematic coherence rarely seen in adult films. Harry Manfredini, the man who became famous for his musical contribution to "Friday the 13th," also composed the music for this sumptuous and original explicit film, a clear inspiration for future productions in the industry. Although conceived as a pornographic film, the high quality of the final production allowed for an erotic version to be made for general audiences. While some of the performances (featuring porn veterans like Terri Hall) are not entirely convincing, other actors are truly magnificent (such as Catharine Burgess herself or the ever-present "villain" Jaime Gillis).
