Operation Clausewitz is in effect. It is April, 20th, 1945. The Soviet Red Army is at the gates of Berlin - over 2.5 million Russians against a force of 150,000 German soldiers; fighting a titanical battle for the Nazi capital. Trapped in the city is Lukas Sonne, a recent conscript of the Volksstrum - the People's Militia with thoughts of deserting to the west, to surrender to the Americans. Will he be able to escape his dying city, or risk dying himself?
