1942, the Great Patriotic War. Returning from a mission, experienced snipers brothers Aleksey and Egor Broshins collide with the German high-class sniper Wengler. As a result of the duel, Egor dies, and Aleksey is seriously injured and ends up in the hospital. Having barely recovered, he rushes to the front, but the medical board recognizes him as unfit. Instead of returning to the front line, the command entrusts Aleksey with an unusual task - to teach young cadets sniper business. Aleksey takes hard, sometimes even cruel, to train his wards.
