Tanki plot
1940. The Soviet Union is on the brink of war and is intensively preparing for it. In Kharkov, the talented engineer Mikhail Koshkin is working on an innovative medium-weight tank. There are two experimental prototypes, but the design is not yet ready for mass production, as not enough has been tested yet. Confident in the possibilities of his design, Koshkin and his team go to Moscow to present the tanks to the country's leadership. However, the Germans find out about the secret development of the Russians and do everything they can to prevent the tanks from reaching Moscow.
