Eskapade (1936)

Miss Mueller, a Polish patriot, employed as a secret agent, is seeking some means of making a safe entry into Czarist Russia in order to help her imprisoned friends. She meets a traveling American, Georg Alexander, and asks his aid to get her into Russia. He allows her to travel on his passport as his wife but after they cross the border she is spotted by Russian agent Walter Franck. Complications follow but she eventually achieves an audience with the carefully-guarded Grand Duke and he promises clemency for her compatriots. She and Alexander return to Poland with the intention of making their fake-marriage a real one.
