December 1944. Soviet troops came close to the city, a strategically important point of the German defense. The city is heavily fortified by the Germans, and an assault can lead to huge losses among the attackers. An intelligence resident operating in the city reports that the entire city is mined by the Germans and will be blown up when the Soviets enter. The reconnaissance group, which received information from him, was destroyed: only one fighter, nicknamed the Artist, survived. He is accidentally found in the forest under the City by another group of scouts led by Lieutenant Papanin, working on their assignment.
