As an orphaned child, Arthur, who was then known as Wart, wants to help his foster brother, Kay, succeed in becoming a knight. While helping Kay train, Wart stumbles upon a cabin belonging to Merlin, a bumbling but talented wizard. Merlin does his best to convince the boy that he is bound for greatness, and when Wart and Kay travel to London to attend a jousting contest, they learn that Merlin was right.
