In the winter of 1939, during the Soviet-Finnish war, a soldier named Zarif from Tatarstan found himself in the crosshairs of a Finnish sniper. Zarif sings a sad Tatar song, which he sang with his beloved Kashifa in peacetime. The Finnish sniper Ziyatdin turned out to be a Tatar, to whom his mother sang this song as a child. This is how the Soviet soldier Zarif and the Finnish sniper Ziyatdin met and became friends. Who are they - enemies or brothers? These are eternal questions to which there is only one answer: the most important thing in your life is love. Everything in your life has meaning only when there is Love in it.
