Een jonge krijger neemt deel aan een vechtwedstrijd en verdient het recht om het legendarische Book of All Knowlege door te lezen. Helaas is het boek in de handen van de tovenaar Zetan en moet de krijger heel wat gevaren doorstaan voordat hij bij het boek kan komen.
Nee, helaas is Circle of Iron nog niet beschikbaar op Netflix in Nederland.
