At the end of September 1941, Soviet artillery troops in besieged Leningrad realize that pretty soon they will fire their last shot, and after that the defense of the city will be doomed. The film is based on a true event: a small group of fearless soldiers transported a large supply of gunpowder through enemy lines to Leningrad.

By a twist of fate, Prince Olensky, a scholar of art history and the director of the Hermitage, is entrusted with the mission of preserving the museum's collection for Russia during the October days of 1917.

A Russian war correspondent is drafted into the war and finds himself in the middle of battle. When he loses his party card, however, he is treated as a deserter until he finds help from a kind man. This Soviet war feature was considerably outspoken for the time as it addressed issues such as anti-Stalinism, Siberia and the inhumanity of war. Adapting his screenplay from a book by Constantin Simonov, Alexandre Stolper was responsible for writing as well as directing.
