Ukraine is in the midst of war. The world's attention is focused on the events at the frontline, where the Ukrainian army is heroically defending its land. But the resistance continues in the temporarily occupied territories. Ukrainians are ready to fight the enemy anywhere and in any way.

This story is about the collision of two worlds. The terrible, brutal, cruel and cynical "Russian world" and the Ukrainian girl, a simple girl who finds the strength to seize the opportunity and take revenge on the enemy for the suffering of her people. Having met a Russian soldier at night by the lake, the girl could have run away and hidden, but she decides to act. The magic of the Ukrainian night, the charm of an incredibly beautiful girl, and her voice mesmerize the occupier. He wants comfort and love with the mythical Mavka, but he gets what he deserves: death for torturing and killing innocent people.
