This romantic musical comedy is set in Paris in 1929. Filled with delightful, witty Cole Porter songs, the story takes place one summer evening in Baron Rommer's elegant penthouse suite at the Hotel Ritz. The baron and his butler switch identities so that the butler can pursue a woman he believes is a lady of a much higher class. It transpires that she is actually a maid in the service of Mme. Baltin, a high society figure who has captured the baron's heart. Her jealous husband and a Baker like actress headlining at the Follies Bergere round out the cast of this door slamming farce with wonderful songs and dancing.
