Making the Grade (1921)

At the behest of his father, fun-loving Eddie Ramson joins an expedition to Vladivostok, Russia, under the command of Captain Carleton. Unable to take his duties seriously, Eddie runs afoul of his commanding officer, but also wins the heart of peasant schoolteacher Sophie Semenoff. A series of merry chases result in Eddie's marriage to Sophie, followed by a brief sentence in the guard house. Eddie returns to the U.S. with his new bride, who is met with disapproval by her snobbish mother-in-law. Sophie is then kidnapped by Soviet agents, but Eddie soon comes to the rescue. Afterward, Sophie reveals that she is a member of the deposed Russian aristocracy, and Mrs. Ramson happily accepts her into the family.
