Marta (Uzbek beauty Anna Khimskaia, perhaps the most gorgeous model Brass has worked with in his recent softcore phase) is a bored wife neglected by her husband, Leon, a lazy, conservative literary editor who, after six months of marriage, doesn't seem to give much thought to the need to continue cultivating passion. His conception of sex clashes head-on with her fantasies, but Marta is a free spirit and unleashes libertine behavior, always under Leon's scandalized gaze. She flirts with anyone who shows even the slightest interest in her voluptuousness and, at a literary party she's forced to attend, she meets Dario, a handsome French artist who, using an overwhelming and enigmatic appearance, practically makes love to her on the spot. Attracted by Dario's audacity, Marta secretly allows herself to be seduced by Leon, who quickly not only suspects but also confirms that she is being unfaithful, through a personal diary that Marta fills out daily with her adulterous experiences (groping, sodomy, threesomes, etc.). In an attempt to pique Leon's interest, Marta tells him about a rape she suffered at the hands of a stranger, but he is so aware of his wife's erotic fantasies that he barely pays attention to her desperate attempts to get his attention.
Tinto Brass is probably best known in the Anglo-Saxon context for the disturbing “Caligula”, but he has a very extensive career that takes him back to the first decade of the 21st century, exhibiting a soft yet explicit eroticism, a kind of subgenre that has not been very common since the 70s. Tinto Brass's unhealthy obsession with asses, female sodomy, voluptuousness and the natural hairy nature of his actresses, together with realistic prosthetic penises (to simulate penetration or fellatio) and almost identical settings and photography, makes it very difficult to distinguish one film from another, encouraging the viewer to adopt the very typical maxim “seen one, seen them all”.
