[3][4] Soviet Scout-translator Captain Igor Volgin receives letters from his artist brother Nikolai, who had been missing since 1942.

At this time, the surviving fascist underground is trying to prevent the Nuremberg process; a traitor officer from the Soviet delegation takes part in it.

Igor Volgin gets acquainted with a Russian girl, Lena, who was taken away during the war to work in Germany and, after liberation, is recruited by the fascist underground.

Igor Volgin takes part in operations to seize the German archive and delivery to the process from Moscow witness - Field Marshal General Friedrich Paulus.

This, as well as the involvement of foreign actors and the need to film abroad, led to an increase in the cost of the project: Prime Minister Dmitry Medvedev approved the allocation of an additional 200 million rubles from the state reserve fund.

The decoration complex “Hall 600” was transferred to the Moscow Patriot Park as a museum exhibit for use in historical and educational work with visitors.
