The opening scene sets the tone of the movie. A scantily-clad woman bicycles up to a house, walks inside and up to a bathroom where the woman of the house is bathing. The bathing woman invites her visitor in, whereupon she steps from the tub, presenting full frontal nudity to her visitor and the camera. The visitor has brought a dress, which she helps the freshly-bathed woman try on. After a quick fitting, the woman removes the dress and dons on a robe instead. The pair then go to the bedroom, where they both end up naked and kissing. Later, the woman's husband arrives and joins the women in bed. No action more explicit than kissing and caressing is shown, though intercourse is implied.
The rest of the movie proceeds to play with similar themes, offering frequent scenes of racy dress through full frontal nudity. Some of these scenes are of casual solo and social nudity, and some show either implied or simulated sexual intercourse. The sex scenes involve both heterosexual pairs, lesbian pairs, and mixed groups of men and women.
In these scenes, we see breasts, buttocks and pubic hair. We see a few glimpses of flaccid male genitalia, but never any erections or female genitalia.
Promiscuity and fidelity are the major themes of the movie. The various couples explore the full range from traditional monogamy to open relationships.
