Daydreams woven in and out of reality soon take over this psychological drama about three middle-class couples on a vacation together at a beach, couples who used to be fired up with liberating ideas in the 1960s but who have now opted for a settled, comfortable lifestyle. One of the men is a doctor who is having an affair with the wife of another of the men, a businessman. The third man is an alcoholic, hoping to garner business favors on this shared vacation. The wife of the unfaithful doctor is a writer -- shy, withdrawn, and aware of what her husband is doing in his spare time. The wife of the alcoholic is hung up on kinky sex. The precarious veneer of normalcy starts to erode when a gorgeous blond arrives at the camp, pitches her tent, and completely unconscious of anyone else, takes off for a nude swim in the water. The next day does not bring her any increased interest in wearing adequate clothing, and soon the men are overdosing on testosterone and their wives are pretending to be too sophisticated to notice the young woman. At this point, the imaginings of the men and women take over -- scenes show them inviting the blond to a dinner that deteriorates into an orgy, or they kill her and bury her body -- is any of that true? More symbolic than it would seem at the beginning, viewers are left to draw their own conclusions as the story approaches its end.
