The Baron of the Locks (1960)

Lucky Baron Jérôme Napoléon Antoine wins a boat in a card game and takes off with his former lover in search of new adventures. Adverse circumstances land them in a small town, where the Baron's seafaring companion departs for more attractive scenery offered by a wealthy local. Meanwhile, there's a certain charming café owner that the Baron finds irresistible – at least for awhile.
