Three young martial arts masters emerge from the back streets of Hong Kong to help the powerless fight injustice.

Twelve-year-old Dre Parker could have been the most popular kid in Detroit, but his mother's latest career move has landed him in China. Dre immediately falls for his classmate Mei Ying but the cultural differences make such a friendship impossible. Even worse, Dre's feelings make him an enemy of the class bully, Cheng. With no friends in a strange land, Dre has nowhere to turn but maintenance man Mr. Han, who is a kung fu master. As Han teaches Dre that kung fu is not about punches and parries, but maturity and calm, Dre realizes that facing down the bullies will be the fight of his life.

It's the 1940s, and the notorious Axe Gang terrorizes Shanghai. Small-time criminals Sing and Bone hope to join, but they only manage to make lots of very dangerous enemies. Fortunately for them, kung fu masters and hidden strength can be found in unlikely places. Now they just have to take on the entire Axe Gang.
