To fix everything, Grozny wants to go back in time with the help of a magical grimoire. However, something went wrong, and Grozny finds himself in our time, where he meets the Osipov family.

But now they are on a journey together to help Grozny find the grimoire and save the prince.

Andrei is now driven by a desire not only to survive, but also to find his father again. To help the protagonist comes his first love, Masha, who in everything that happens also has her own interest.
