The film tells the story of the Podolsk cadets' heroic stand outside Moscow in October 1941. Cadets from the Podolsk infantry and artillery schools were sent to the Ilyinsky line of defense, fighting alongside units from the Soviet 43rd Army to hold back the German advance until reinforcements arrived. Hopelessly outnumbered, young men in their teens laid down their lives in a battle lasting almost two weeks to obstruct the far superior German forces advancing towards Moscow.
