Please answer this: Generate a question that has the following answer: seven for the following movie plot: In 1942, both Nazi Germany and the Soviet Union are gathering forces and supplies in one particular sector of the Eastern Front for a major attack. The Soviets are secretly constructing a bridge at night over a river. To avoid detection, it is being built underwater, just below the surface. In an attempt to find out where the Germans plan to strike, Colonel Semenov (George Macready) has a small paratrooper unit dropped behind enemy lines to attack a divisional headquarters and hopefully take an officer prisoner for interrogation. The local partisans, led by the wily Kostyuk (Roman Bohnen), provide a guide, Lisa Elenko (Marguerite Chapman). The attack succeeds at first. Alexei Kulkov (Paul Muni), one of the paratroopers, takes seven Germans prisoner in the basement. Then, just as Elenko brings him a message, German artillery hits the building, causing it to collapse and trap them in the spacious cellar. Afterward, Kulkov's dog sniffs out where his master is buried and starts digging. This alerts one of Kulkov's comrades, who communicates with him by tapping on a metal pipe in code. Learning that Kulkov has caught an officer, he leaves to get help. Kulkov is in no hurry to dig out. Though the prisoners rank no higher than a sergeant, he is convinced one of them is an officer in disguise, based on a pistol and a monocle he has found. He begins questioning the men one by one, but while he rules out ex-miner Stillman (Rudolph Anders) and a former magician (Philip Van Zandt), he cannot pinpoint his man. An eighth German soldier, thought to be dead, wakes up and attacks. In the struggle, the lone lantern is extinguished and Elenko is stabbed in the shoulder. However, Kulkov kills him and regains control of the situation. Oddly, Elenko is certain that one of the Germans tried to help her in the darkness. Kulkov decides to try a ploy. He orders the magician to go around the corner of the main room out of sight of the others. He knocks the German out and then fires one round, making the rest think he has exacted...
