There is an iron rule in the Ching Hing Gang: No drug dealing. The gang leader, Yu Nam (by Kent Cheng), has two right-hand men: one is Tin (by Andy lau), a bright and sober adherent of principles and loyalty; the other is Jizo (by Louis Koo), a cold-blooded smart man who secretly r
uns a drug business without Nam's knowledge. Ordered by the top leader, Tin teaches Jizo a lesson by cutting off one of his fingers and expells him from the gang. Fifteen years later, Jizo becomes the biggest drug dealer in Hong Kong; while Tin has established himself as a financial tycoon and a philanthropist, and is offering a $100 million bounty to eliminate the No.1 drug dealer in Hong Kong. Inevitably, a battle between the two tycoons is underway.
