A new Lieutenant Kravtsov is sent to the front lines to command a platoon. Knowledge of the statute, a high sense of patriotism, strength and youth – the lieutenant has it all. He only does not have combat experience. And according to statistics, in a combat situation platoon commanders do not live more than three days. Only these three days are not simple. They are akin to a lifetime in which one has to be born as a soldier first, to grow up and become a fighter, and then, with luck, become the commander, who will lead the soldiers. That's why the war has it as the song says – "Moments are compressed in years, moments are compressed in centuries."
