The film is the last silent film directed by Lewis Milestone, the last silent performance by Gary Cooper, the last silent performance by Germany's Emil Jannings, and the only onscreen pairing of Cooper and Jannings. It is considered a lost film.


Swiss peasant girl Vroni (Esther Ralston) is having a secret summer romance with Viennese artist Andre Frey (Gary Cooper). When Andre later returns to Switzerland, he learns that Vroni has been forced to marry wealthy burgomeister Poldi Moser (Emil Jannings). Explaining Andre's appearance, Vroni introduces him as a young man who has just lost his sweetheart, and in sympathy, Poldi invites Andre to be a guest in his house.
