Hector and Odette Dupuis' car breaks down in the middle of nowhere, but not far from a luxury hotel. The couple are well off but, being miserly, Odette is determined to keep her budget tight. Fortunately for her, the hotel offers rooms for domestics costing only 35 francs, so she decides to pass her husband as her chauffeur.

The jealous guy steals a jewel from a guest and has poor Hector accused of the theft.
