Le fraudeur (1937)

Florimond, a dangerous smuggler, and his mistress Viviane try in vain to transfer illegal precious stones. When Viviane gets to know young Théo, a naive young peasant, she immediately capitalizes on the encounter. Thanks to her charm, she seduces him into becoming her accomplice. And, naturally, the operation is a success. Unfortunately for Florimond and Viviane, things soon go awry. Indeed, Théo's godfather, a customs officer, who has heard of the affair, lectures Théo and makes him become aware of the offense he has committed. The young man now wants to makes amends. Which is not to Florimond's liking.
