The Princess Marya and her brother, the Grand Duke Paul, are in America studying American institutions when word comes to them that the death of Rasputin will be a signal to them to return to Russia. Paul is seized by Russian secret service men, but released by Capt. Willard, to whom Mary appeals. Later the three come together in Russia, where Marya is now one of the Revolutionaries and Willard one of the Allied Commission.
