In a manor in the Pyrenees, six people gather for the reading of a will: The mistress of the house, Milena (Françoise Brion), her cousins Séraphine (Alexandra Stewart) and Jean-Paul (Paul Guers), her lawyer and her servants, Prudence (Bernadette Lafont) and Cesar (Michel Galabru). Couples form for a night, and at dawn, the masks come off. With music by Serge Gainsbourg.
