When King Gerlach dies, he asks Merlin the Magician to care for Baby Arthur and do his best to see that when Arthur is grown, he takes his rightful place as King. Despite Arthur's entreaties to Merlin to let him become his apprentice, Merlin insists that there are more important things in store for him. When Merlin nominates Cynthia as his new apprentice, Arthur leaves in search of his destiny. Soon after, he is captured by the evil Sir Baldrick and left in a dungeon to be devoured by a dragon. Fortunately, Cynthia, using her magic powers and guile, frees Arthur in time for him to go to Stonehenge and compete with the Knights of the Realm who try to pull the sword from the stone to become King. Of course, Arthur easily removes the sword and is crowned the new King.
