Curious schoolboy Senka by some miracle finds himself in a fabulous ancient forest. It is hidden from human eyes by a powerful spell of Baba Yaga, designed to protect people and the whole world from the dark forces dormant there. There is clearly something wrong in the forest. Alarm signals herald that the spell no longer works and the awakening of sinister magic and enemies long defeated is only a matter of time. In order to cast the spell again, Yaga is forced to travel to a modern city in search of the most powerful weapon of wizards, the marvelous flower. There she will meet with many quirks of the modern world, and in a dark dungeon Koschei the Deathless has been hiding for a thousand years, thirsting for revenge, because it was Yaga who helped defeat him many centuries ago. Senka got into a fairy tale, but will he be able to escape back, help save our world and on whose side will he take the fight - good or evil, the almighty Koshchei or the cunning Yaga?
