Our days. Curious schoolboy Senka finds himself in a fairy-tale forest, hidden from human eyes by the spell of Yaga. To cast the spell again, Yaga goes to a modern city in search of a magical wonderful color. In the city, Koshchei, who remained alive after the battle with Ivan Tsarevich, has been waiting for a meeting with Yaga for a thousand years. Koschei is hiding in a dark dungeon and wants revenge, because it was Yaga who helped defeat him. There will be a new battle of good and evil. The winner will be the one who will be supported by the schoolboy Senka, who until the last did not believe that he was in a fairy tale.
