Welcome to St. Jude, a town where rival gangs rule the streets, where the chief of police is a cold-blooded killer, and where citizens have learned to keep their heads down. Then comes out-of-towner Ryan Hong. His vintage car attracts attention. His unbelievable martial arts skills cause a sensation. Sensing a human weapon, the rival gangs bid for Hong's allegiance. But Hong is committed to honoring an old promise to a mentor he met in prison: that he will "do good" wherever possible.
