Helene De Travillac, a sweat little French girl, loves her handsome cousin, Andre D'Eguzon, but a scheming aunt has engaged her to Valentin LeBarroyer, a methodical, statistic-loving "stick," but wealthy. On the wedding morning Andre suddenly appears on the scene and pleads with Helene. She hesitates, a little, tears off her veil and flees with her lover to her old home in the country. There her grandmother makes the natural mistake of thinking Andre is the husband. The resulting complications are amusing. Finally arrives the discarded Valentin, hunting for his bride. When he dins her he proves himself a man, and "The Beautiful Adventure" ends happily for the lovers. This film is presumably lost.

Adventuress Leonie Sobatsky falls in love with a young man named Nevil Trask, and he with her. Trask doesn't know that Leonie is actually the head of an international smuggling ring--and Leonie doesn't know that Trask is an undercover Secret Service agent assigned to break up the ring and capture its head.
