Gigolo (1926)

The heir to a family business travels to Paris to try to stop his youth-obsessed mother from squandering the family fortune with her new husband, who married her for her money. After he returns from service in World War I, he finds his mother broke and abandoned by her gigolo husband. In an ironic turn of events, he winds up squiring rich old women around Paris' nightlife, becoming the kind of gigolo from which he tried to save his mother. Things take a turn for the worse when some family friends from back home turn up in Paris and see what has become of him.
