The Baron of the Locks
Le baron de l'écluse (original)
The lucky Baron wins a boat in a card game and takes off with his former lover to find new adventures. Adverse circumstances land them in a small town, where the Baron's seafaring companion leaves for more attractive scenery offered by a wealthy local man. Meanwhile, there is a certain charming cafe owner that the Baron finds irresistible -- at least for awhile.
