Lieutenant Colonel Nechvolodov, commander of a self-propelled artillery division, even in his worst dreams could not imagine that he and his unit, instead of being at the WEST-81 exercises, would end up in 1941 near Vladimir-Volynsky and would fight with Wehrmacht. This is how the exciting action begins. About two hundred soldiers of the Soviet Army are confronting the incalculable might of Nazi Germany, namely Army Group South. At the same time, Nechvolodov realizes that, while defending his homeland, he is simultaneously interfering in history, the consequences of which he cannot predict. The officers and soldiers of his division help him in this.
