For 60 years, a mysterious monk with no name (Chow Yun-Fat) has zigzagged the globe to protect an ancient scroll -- a scroll that holds the key to unlimited power. Now the Monk must look for a new scroll keeper. Kar (Seann William Scott) is an unlikely candidate, a streetwise young man whose only interest is himself. But when he inadvertently saves the Bulletproof Monk from capture, the two become partners in a scheme to save the world from the scroll's most avid pursuer.
