Caroline, Hélène and Dorothée are on vacation by the sea. A violent storm rises and they find themselves separated. In the morning, Caroline is spotted by a young man who leads her to a hut. A little later, she comes to herself, alone and naked in this hovel. She wears a dress that drags there, goes out and soon finds her friends. They are on the island. All three then approach a superb house where a young woman plays the piano. They arrive at the port and learn that the next boat for the continent does not leave until the next day. Without money, without lodging, they decide, under the impulse of Dorothée, to accept the proposals of three boys of the place, Max, Etienne and Raoul. Etienne is fascinated by Caroline whom he saved a few hours earlier. But she only thinks of the man in the villa. The three boys invite the three girls to extend their stay on the island and go with them to the mainland to collect their belongings before installing them in a comfortable little house. Max and Raoul assiduously court Hélène and Dorothée; Caroline will meet Jordan and his wife Julia, the pianist. The girl enjoys their company and refuses all of Etienne's advances. When Julia leaves to give a concert in Caracas, Caroline is delighted to stay with Jordan. And when we learn that Julia died in a plane crash, Caroline, to console Jordan, offers herself to him.
