Tri dnya leytenanta Kravtsova

Platoon commander Lt. Kravtsov reports for active duty. Military 'fate' allocates for such lieutenants only three days of life, on average. During this time, Kravtsov should become the commander of his troops and lead them in a hopeless attack, to save the regiment coming to the rescue. The question is, can he survive in these three days? It all seems so unfair - to die at the age of eighteen.
