In an early scene, Karen (Luan Peters) displays rear and upper nudity whilst taking a bath. Later, she takes another bath, again displaying upper nudity and a very brief full frontal (possibly because she failed to position her towel properly. We see upper nudity a further time when she is spied upon by a peeping tom.
The central story arc concerns marital boredom and infidelity, so Karen does eventually stray. She is shown removing her bra, and having her breasts both caressed and kissed by her lover, Alex (Vincent Ball). Unbeknown to her, the encounter is being photographed by Eddie (Sean Barry-Weske), the guy who was spying on her earlier.
Karen attempts to interest her husband in oral sex, unsuccessfully (nothing explicit is shown).
A photograph of her infidelity is used to blackmail Karen into attending a sex party, hosted by Suzanne (Fiona Richmond, curiously using the name 'Amber Harrison' whilst keeping her clothes on for once). A woman is shown topless, dancing; later, she is shown having sex with one of the male guests (side nudity from both, rear from him. Karen watches, but is not shown taking part.
Her husband is taken to a strip club by a business client, where they watch two topless dancers (the Tiffany Sisters, which they are also called in the film; there is brief frontal nudity at the end of the act). A movie is screened; after the title card "Willing Flesh" (held by the woman we saw at the party, topless), there is footage shot at the party. Karen is seen being persuaded by the same woman to join the orgy. Her husband recognises her among the thrashing limbs (I couldn't) and runs into a toilet to throw up.
Karen goes to a health club with her friend Joan (Nicki Howorth and is seen lying face down on a massage table whilst naked. Joan is topless. Two women shower in the distance, but we only see their vague silhouettes behind a curtain.
Karen and her husband argue, and he tears open the front of her top, exposing her bra and cleavage. She telephones Joan to warn her about the film, and Joan in turn calls Alex; a woman can be seen using Alex's shower, exposing side and rear nudity, then a brief full frontal as she moves out of shot.
The outraged participants in Alex's parties get their revenge upon him and his partner for filming them. The two men are thrown naked from a car into a remote field. There are distant shots of both, rear and front, as they chase after the departing vehicle.
The film closes at a fireworks display, with Karen wondering if she has any chance of saving her marriage.
