Orville works as a piano teacher and songwriter in a small town. One day, he finds himself obliged to host a famous singer and renowned Don Juan in his house. This might be the chance to make him listen to his songs and become rich, but the risk that he could seduce his wife is too big. To protect her, Orville prepares a set-up: he replaces his unaware wife with the docile waitress of Belly-Button Café.
