The Surveyors (1972)

Lucien asks a friend, Léon, to carry to the woman he desires, Alice, a basket of provisions and to thank him for it offers him its cap. Léon seduces Alice, small brunette and admits later to his friend his "overflowings". Léon returns at Alice's home but it is not any more the same person; she is blonde and bears no resemblance to the woman the day before. One is sensual and welcoming, the other, mysterious and independent.
