Somewhere in the Forbidden Forest lives a wicked sorcerer Kruciatus. One hundred years ago he tried to destroy a kingdom now ruled by King Alexander, who has two sons - the heir of the throne Prince Jan and the younger Prince Karel. Karel is not satisfied with his role of the underrated second-placer. With the help of his servant Pakosta, 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.
