The whimsical Jean Latour wins a competition for a month's holiday on the Côte d'Azur. When he arrives at the "Villa Sans Souci", he discovers that the owner and generous donor, M. Mallez, is a doctor, that the property's guests are sick with nerves, and that Mallez has brought him in to entertain his neurasthenic residents.
