Edward and Caroline

Edouard is a pianist, married with Caroline. This evening, they are invited to Claude's. Claude is the snobbish uncle of Caroline, his son Alain is in love with Caroline, and they spite Edouard because he's poor. At the party, Edouard must play the piano to make himself known by Claude's important acquaintances. But just before leaving, Edouard and Caroline quarrel about clothes, and Edouard goes alone.
