The Legend of Prince Valiant

Prince Valiant receives an invitation to the wedding of an earl's daughter in a distant territory. In the forest near the earl's castle, Val is ambushed by a band of thieves, led by the giant Horack. Val is stripped of everything, including his shield, sword, and his horse, Caliburn. When he staggers to the castle, the guards, taking Val for a vagrant, deny him access to the wedding.
