[1] The teenage Chris is on holiday at Saint-Tropez with her mother Claude, while her father remains at work in Paris.

Initially she falls for the older Romain, whose interest is in supplying young girls to rich men.

For himself, Romain is far more interested in the mother Claude, who gradually thaws to his approaches and becomes his enthusiastic lover.

Put out at this, Chris befriends a German married couple but, after a threesome in their hotel room, the husband leaves in disgust.

While starting a romance with the abandoned wife (Barbara), Chris murders Romain in order to thwart her mother.
