In 1919 Latvia, a detachment of German Freikorps soldiers is stationed in a chateau in the town of Kratovice to fight Bolshevik guerrillas. The chateau is the home of the soldier Konrad de Reval and his sister Sophie de Reval. Sophie is attracted to another soldier, a close friend of Konrad's named Erich von Lhomond. However, the reticent Erich rebuffs her advances. In retaliation, Sophie has trysts with other members of the military troop. Erich is noticeably angered by her behavior. Eventually, Sophie learns that Erich and Konrad are lovers. After this discovery, she joins the leftist guerrillas, whom she had been in contact with previously. Erich's soldiers capture her and her comrades. Sophie asks that Erich execute her himself, and he obliges. In a striking single tracking shot, we see Erich casually shoot Sophie in the head before joining in a photo with the other soldiers. As all board a train, the camera pans back to the corpses of the executed.
