Princess Marya and her brother, the Grand Duke Paul of Russia, are studying in the U.S. when word reaches them that Rasputin is to be killed. Paul is seized by Russian secret service men, but through Marya's appeal to Captain Rodney Willard, he is released. In Russia, Marya participates actively in the Revolution, while Willard, with whom she has fallen in love, joins the Allied Commission. Deeply troubled by the influence of German agents in Russia, Marya organizes the Legion of Death, a fighting unit of peasant women, and leads them into battle against the Germans. The legion suffers defeat and Marya is captured, but in the end, she wins her freedom.
