In a mystical desert kingdom, young martial arts fighter Cord loses a contest to determine who will journey to take the powerful Book of All Knowedge from Zetan, an evil wizard. Despite his lack of a sponsor, Cord's rule-breaking nature leads him to try retrieving the book anyway. Help is offered by a mysterious blind man who gives advice as Cord fights his way through multiple opponents, discovering more about himself as he gets closer to Zetan.
