On a summer day at the house of Rodolphe, a rich friend, Adrien and his fiancée part on strained terms. She has to go and work for five weeks in
London, while he chooses to spend the time at a house Rodolphe has rented near
Saint-Tropez. Also there will be another old friend, Daniel, and the two men can just relax by reading and swimming. When he gets there, Daniel warns him that unfortunately there is a third occupant. This is Haydée, whom Rodolphe has bedded and who now brings a different boy back each night. The two friends unite in banning any more boys and gating her, while bullying the decade younger Haydée by branding her a little
collectionneuse, a collector of men. After sulking a while, Adrien turns his charms on Haydée. While he admits to her that he likes her greatly, he says his moral code will not allow him to sleep with her, so he tells her to seduce easier prey in the shape of Daniel. The two sleep together for a while, but the fastidious Daniel turns against her and, after insulting her, leaves. Adrien comforts the hurt girl and thinks of a new plan to interest her. He has brought with him a rare Chinese vase to deliver to a rich but crass American collector called Sam, who is struck by Haydée. Sam invites the two to his villa to have dinner and stay the night. Adrien agrees with Haydée that he will plead he has business in the morning and will leave her there to seduce Sam. Going back to fetch her next evening, Sam turns against Adrien and insults him while flirting with Haydée, who then knocks over his precious new vase. The two make their escape and, as they drive home, Adrien thinks she is good at heart and now that Daniel has gone he can spend the last week of his holiday in an enjoyable affair with her. Two men passing by in an Italian sports car recognise Haydée, who runs out to talk to them. When they invite her to join them in Italy, she takes her overnight bag out of Adrien's car. Adrien, after waiting a while, leaves her with them and returns to the empty villa alone. He can now fulfill his aim of peacefully reading and swimming, but it is not what he wants any more. He picks up the phone to book a seat on the next plane to London. ==Cast==
