Cavalry captain Michael von Prack, a daredevil pilot in
World War I, is taken prisoner by British troops in
Asia Minor in 1918. He seizes the chance to escape to his homeland
East Prussia with a ready-for-take-off British plane. At home, he gets caught up in the post-war turmoil. In a bar, Michael comes across a captain who is recruiting former
regular soldiers to fight in a
Freikorps aligned with the
White movement against the
Red Army. Michael joins the troops and, at the same time, meets lovely Vera Iwanowna. She considers him to be his cousin, Russian general Alexej Alexandrowitsch von Prack, with whom she is in love, because the two men are as like as two peas. Alexej, who cannot stand his cousin Michael since their childhood, commands the Russian troops standing against the Freikorps. While moving forward into the warzone, Michael re-meets Vera who is not only Alexej's lover, but also a Russian
spy. Meanwhile, she has learned that he is Alexej's German cousin, but nevertheless spends a night with him before returning to the Russian headquarters. When Alexej learns that Vera has met his hated cousin who is the commander of the enemy troops, he swears him death and sets a trap for the Freikorps by luring them into a
swamp. In this situation he demands Michael to meet him personally, and the two men fight against each other. Alexej dies, Michael is severely wounded. Because the latter is not wearing his uniform jacket, the Russians consider him to be the general and take him to their headquarters. Although Vera recognizes him immediately, Michael is able to act as the general and to discover important military secrets. He also gives the Russians orders that improve the situation of the Freikorps. Meanwhile, Vera is wavering between love and
patriotism. Finally she reveals everything to the Russian
commissar because her patriotism is stronger than her love to Michael. The latter is, however, able to escape and to return to his soldiers before being arrested. Now that they know the deployment plans of the Russians, the Freikorps attacks them from the back. Michael is killed in battle, Vera dies when the Freikorps shells the Russian headquarters. == Background ==
