Checkerboard(1959)

Original title: Les tripes au soleil

In a small Gallic village, tourists are regaled by street entertainers and brash prostitutes. One of the tourists, a black girl named Bessie, falls in love with local villager Bob, and he with her. Soon racial tensions erupt volcanically among tourists and townsfolk alike. All is forgiven when the respective parents of the hero and heroine save the village's water supply.
