Delphine (Catherine Deneuve) and Solange (Françoise Dorléac) are twin sisters who each want to find romance and leave their small seaside town of Rochefort, France. Soon they befriend a couple of visiting carnival workers who frequent their lonely mother's (George Chakiris) café and hire the girls to sing in the carnival. Wanting a career as a songwriter, Solange falls for an American musician, Andy (Jacques Perrin), while Delphine dumps her beau and searches Rochefort for her ideal man.
