Alexandra Barnes (Debra Winger) lowers herself to perform CPR on Catherine Peterson (Theresa Russell), revealing deep cleavage, as the women practice mouth-to-mouth resuscitation on grass during a scuba diving class; Catherine wears a strapless bra, and their intimate proximity, combined with playful dialogue about "not taking the gesture personally," establishes clear sexual tension and parallels between mouth-to-mouth and kissing.

At a wedding party, Catherine (Theresa Russell) confronts Alexandra Barnes (Debra Winger) during a tense exchange about motives and suspicions, then abruptly and firmly kisses Alexandra on the lips, highlighting the underlying sexual tension and psychological complexity between the two women.

Catherine Petersen (Theresa Russell) sits on a hospital exam table wearing a gown open at the back, revealing her bare back and the upper portion of her buttocks above small panties.

Catherine Petersen (Theresa Russell), draped in a blanket near the fireplace, lets it fall to reveal her bare buttocks and a fleeting, partial glimpse of labia, then moves into bed beside William McCauley (Nicol Williamson) where her bare breast is visible as the couple engage in sensual kissing, physical caressing, and close body contact, with the scene emphasizing nudity and erotic intimacy.

Catherine (Theresa Russell) is shown fully nude as she steps into a pool, exposing her back, buttocks, and frontal nudity with her legs spread widely and a blurred view of her pubic area underwater while swimming; Paul Nuytten (Sami Frey) joins her nude off-camera, and they make out and engage in prolonged sexual contact in the pool with both actors' backsides and Catherine's full-frontal nudity clearly visible, emphasized by close, continuous shots throughout the extended scene.

Most of the violence in the film is done through poison and not really shown. At one point though, a woman holds a gun to a man's head and forces him to take a drug overdose; he is visibly upset and afraid.

Some religious profanity is used (mostly 'Goddamn').

Several uses of swear words, including f**k.

A good deal of smoking and at one point we see a man take a lethal drug overdose. His actual death is not seen; we see before and after.

The antagonist of the plot is apparently a psychopathic, femme fatale named Catherine who preys on wealthy middle-aged men, seducing them into marriage and then fatally poisoning them. Each death is misdiagnosed as Ondine's curse, a condition by which seemingly healthy middle-aged men die in their sleep.
