Madame (1961)

Original title: Madame Sans Gêne

Catherine Hubscher, who washes the shirts of young Napoleon and other soldiers fighting the Revolution, falls in love with Sergeant Lefebvre. Circumstances bring Lefebvre a noble title and even more -- Napoleon decides to make him the local ruler over a large territorial fiefdom. But trouble brews when Madame Sans-Gene, now elevated to the nobility along with her man -- cannot keep her frank observations under control.
