He lives with his mother, goes to school, hooligans moderately and smokes weed, in general, he is an ordinary boy. Russian boy in Denmark.

But then mom gets married again, and they move into the house of a new stepfather. Beautiful, big and... hiding a dark secret behind a locked door. Life - and not only his own - will soon depend on whether Jack can solve it.
