The notary Tremplin wants to give his daughter to the young rich farmer Adhemar. He goes with both of them to Paris where Henriette meets a sleazy car salesman who is precisely the rich heir sought by her father.

To come into possession of an inheritance, a young woman must marry a man she does not love and who does not love her either. But he falls in love and manages to conquer his wife by becoming a totally different character from the one he was at the time of the wedding.

While walking back home at night, an examining judge is robbed of his watch. Fortunately he offers resistance and, by roughing up the mugger, manages to recover his belonging. Imagine his surprise when he realizes his thief is none other than... the President of the Court of Justice! How will the poor man behave with him knowing what he knows?
