The White Storm 2: Drug Lords

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 Dizang (by Louis Koo), a cold-blooded smart man who secretly runs a drug business without Nam's knowledge. Ordered by the top leader, Tin taught Dizang a lesson by cutting off one of his fingers and expelled him from the gang.
