Korunní princ (2015)

Somewhere in the Forbidden Forest lives the evil wizard Kruciatus. A hundred years ago, he attempted to destroy the kingdom now ruled by King Alexander, who has two sons - the heir to the throne, John, and the younger prince, Charles. However, Charles refuses to accept his role as second in line at any cost. With the help of his servant Pakosta, he breaks into a forbidden chamber in the castle, obtains magical props left behind by the evil wizard, and intends to destroy his brother. Prince John drinks a magic potion served to him by his mischievous brother, which instantly erases his memory. John then recklessly sets off on a journey to the Forbidden Forest, where everyone who has ever entered has disappeared without a trace.
