Somewhere in the Forbidden Forest lives a wicked sorcerer Kruciatus (Josef Abrhám). One hundred years ago he tried to destroy a kingdom now ruled by King Alexander (Jaromír Hanzlík), who has two sons - the heir of the throne Prince Jan (Patrik Dergel) and the younger Prince Karel (Krystof Hádek). Karel is not satisfied with his role of the underrated second-placer. With the help of his servant Pakosta (Pavel Kríz), he breaks into the forbidden chamber full of magical properties, remaining there after the evil wizard, and intends to destroy his brother in order to get the throne for himself.
