Henri Durand of the French nobility is insanely jealous of his beautiful American wife Marion's innocent conversations with her many male admirers. Durand provokes her suicide when, egged on by a rejected suitor of Marion's, he accuses her of having illicit relations with her visiting childhood friend, Tom Franklin. Twelve years later, when Tom returns after a long expedition, the vengeful Durand coaches his daughter Beatrice, who resembles Marion, to court Tom. After they become engaged, Durand forces Beatrice to flirt with other men, but when Tom, overcome with jealousy, is about to kill himself, Beatrice admits her real love for him. Durand is at first furious with Beatrice's supposed betrayal, but he is pacified when he receives a confession from Marion's refused suitor that absolves Tom of any guilt. Durand then permits the marriage of Beatrice and Tom.
