A shadow has fallen over humanity, and the hope of the world is on the return of a legend.
An evil wizard threatens to take control of the world, and he has the powers of Hell behind him. The fate of humanity rests on the shoulders of an unlikely hero, small-town teenager Jason Campbell. What Jason doesn't know, is that he's the reincarnation of the legendary King Arthur.
With the help of the wizard Merlin, Jason ventures to the mystical realm of Avalon. There he hopes to reclaim his birthright, the sword Excalibur, with which Jason must defeat the darkness that has fallen over mankind.
