Les Nouveaux Maîtres1950

Durand, a big industrialist, works with an international adventurer, Mr. Ernest, who covets Mrs. Durand and threatens to bankrupt her husband if she does not consent. She calls him a jerk. Mr. Ernest sets out to ruin the Durands, and leaves in the castle that they must sell their couple of servants, Victor and Marie, who become the new masters, at the same time as they serve as a screen for Ernest for his dubious business.
