The modern guy Alyosha is far from myths. But even he notices the changes in his native Kalyazin, since the doors of the old Research Institute have reopened.
Is the invasion of hogweed fake or dark magic? While the institute is looking for traces of the witch, Alyosha encounters them by chance - in his own house.
No one is in a hurry to help Alyosha - it's time to get down to business yourself. The director of the Kozyrev Research Institute sends people to search for the lost magic stone.
According to science, for every action there is a reaction. Alyosha, Ilya and Nikita only need to understand what to counter the dark power of the witch.
The team is divided: Ilya is looking for a witch, Lyokha turns to the lost knowledge. But in the pursuit of the past, he risks losing the most precious thing.
It's time to meet the witch face to face. Lykha, Nikita, Ilya and others marked by Alatyr are waiting for a new discovery - and it can change everything.
