Les voyeuses (1978)

Hélène, the chemist of the village, and the priest's sister. Olga, a nun who lives with the priest. The priest is a funny fellow who seems to enjoy talking about sin and about wine being Christ's blood. At the hotel, the wine merchant gets acquainted with Ginette, a black maid, and asks her about the nice lady he's met. His description fitting the maid perfectly, she offers her slender body for his wristwatch. It's a deal. André's wife, who is a friend of hers, invites Ginette to her place and in the meantime, takes care of herself.
