The Young Girls of Rochefort 1967

A group of traveling musicians arrives in a small seaside town near a Navy base to put on a carnival. Among the guests are two young men, Étienne and Bill, who were recently dumped by their girlfriends, who ran off with sailors. To put together a musical performance, the young men have to turn to the local twin sisters, Solange and Delphine—who are also musicians—for help.
