Paris-Camargue.

In the Camargue, the rich owner Jules Fabregoul squanders all his fortune to please his mistress, a Parisian actress with luxury tastes. But he is not the only one to be in trouble. His niece is having sentimental problems: she thinks she is being cheated on by her fiance Gérard, a music-hall artist. She takes refuge with Jules's sister, Aunt Fabregoul, the director of a home for repentant young girls. But Gérard did not make a mistake and the reconciliation takes place during the recording of a radio program.
