There is an iron rule in the Ching Hung Gang: No drug dealing. The gang leader, Yu Nam, has two right-hand men, Yu Shun-Tin, smart and sober adherent of principles and loyalty; the other is Jizo, a cold-blooded but wise man who secretly keeps running drug business without Nam’s knowledge. Years ago, a police couple, Fung and his wife, was inspecting Jizo’s nightclub, and the wife was killed in the operation. On the same night, ordered by the top leader, Tin taught Jizo a lesson by cutting off one of his fingers and expelled him from the gang. Meanwhile, due to Tin’s dangerous lifestyle, his girlfriend vanished without a trace. After that, Tin swore to change sides. 15 years later, the local drug market is now quadripartite. Jizo becomes the biggest drug dealer in Hong Kong, while Tin has now changed into a financial tycoon and a philanthropist. Tin is offering a 100 million bounty to eliminate the #1 drug dealer in Hong Kong. It causes a stir in the society and underworld. Inevitably, a battle between the two will ignite!
