A peasant named Ho (Lui Leung-Wai) travels to Hong Kong from mainland China looking to succeed in the criminal underworld. The streets already run rampant with Triad gangs, so Ho makes a deal with Boss Kun (Kent Cheng). If he can seize control of the district of Sham Shui Po from Kun's rivals, he will be put in charge of it. Ho accomplishes this feat violently, and his cold-blooded ruthlessness helps him rise up through the syndicate's ranks. Unfortunately, his vices threaten to bring him down.
