Celestine, the chamber-maid, has a new job in the country, at the Lanlaires. She has decided to use her beauty to seduce a wealthy man, but Mr. Lanlaire is not a right choice: the house is firmly controlled by Madame Lanlaire, helped by the strange valet Joseph. Then she tries the neighbour, former officer Mauger. This seems to work. But soon the son of the Lanlaires comes back. He is young, attractive and does not share his mother's antirepublican opinions. So Celestine's beauty attracts Captain Mauger, young Georges Lanlaire, and Joseph. Three men, from three different social classes, with three different conceptions of life. Will Celestine be able to convince Georges of her sincerity?
