The king of the streets (2012)

Yue Feng is a young thug with exceptional streetfighting abilities. He will stop at nothing to defeat all challengers - until, in an tragic accident, he kills a fellow competitor and is sent to prison. Eight years later, Yue Feng emerges a changed man. He no longer fights, and is looking for a new life of peace and fulfillment. But it's brutal on the streets, and redemption doesn't come easy. His brotherhood is destroyed, family members murdered, and a loved one humiliated - a deadly chain reaction that leaves him no choice but to unleash his power in the name of justice.
