Plot

1943. On the eve of the Red Army offensive, Captain Belov's group, which includes Ivan Rodin, accidentally discovers a disguised tank division near the village of Anino. The scouts understand that only they know about the ambush arranged by the Germans. The wounded Belov orders Ivan to reach the Soviet command and warn them of the danger. He reports to the headquarters about the tanks he saw and even reproduces the tactical number of the division, but the front command does not believe him. Suspecting Ivan of misinformation and working for the Germans, the military sends him under arrest. Colonel Alyoshin tries to save his friend: thanks to his perseverance, the command sends another group to Anino — Ivan becomes the guide, and Odintsovo leads the detachment.
