Young huntsman from the hunting farm lost in the remote Karelian forests Kostya Mishutin, faced in impassable more often with "reenactors" dressed in the pre-war uniform of the Red Army, decided, for fun, to play along with them and to the formidable shout "Stop who is coming?!" replied: "Defector from Finland! I don't want to fight the Soviet Union!" Only a few hours later Kostya realized that the thousands of armed people in authentic uniforms that he saw were not playing "war." There really is a real war around, later nicknamed Winter. And the abilities of a huntsman who knows how to "listen to the forest" are very useful in the hunt for enemy snipers, nicknamed cuckoos, terrorizing the fighters of the Red Army.
