He accidentally meets a real witch and, through her fault, ends up in the body of a serf guy from a parallel World stuck in the Middle Ages. Not wanting to spend his whole life poking around in the ground, Sergei tries in any way to get rich and become a noble nobleman. And this business is very complex, dirty and very dangerous. After all, people like him are just pawns in the games of the powers that be.
