Synopsis

Ching is a prisoner in a Honk Kong jail that has a large population of Mainland Chinese prisoners. Ching escapes to see his young son, who he has been put in an orphanage. He surrenders himself to authorities, but the vengeful chief of security, Zau, arranges for Ching to be set up in the eyes of the Mainland gang, led by the affable Dragon. Dragon and Ching both then escape separately, and while fugitives, hook up together and bond. Ching is recaptured and instigates a riot to save his own hide from the Mainlanders. In the chaos Ching gets revenge on Skull (who, working with Zau, set him up) and Zau
