The Monk (Chow Yun-Fat) is a Zen-calm martial arts master whose duty has been to protect a powerful ancient scroll. Faced with finding the scroll's next guardian, the Monk's quest brings him to New York City where, to his disbelief, it appears his successor is a smart-mouthed pickpocket named Kar (Seann William Scott). Kar's a charming, street-tough wild card who enjoys his life of no responsibility. As the Monk instructs Kar the unlikely duo becomes partners in protecting the scroll from a power-monger who's been chasing it for 60 years. Amidst high-flying acrobatics and martial arts actions, this comical odd couple has to work together to keep the scroll - and mankind - safe.
