Synopsis：During a police crackdown on a drug cartel, an undercover narcotics officer infiltrates the organization to carry out anti-drug operations. After the first-generation drug lord dies in a shootout with the police, a second-generation drug lord known as the Dean (played by Eric Tsang) quietly rises to power. Eager to expand his influence, the Dean sets his sights on third-generation drugs. He arranges for his subordinate (played by Chen Long) to go undercover and get close to the genius drug chemist Brother Hua (played by Ray Lui). When Brother Hua, hailed as a drug-making prodigy, produces a super drug of astonishing purity, the game between two major drug trafficking groups officially begins. With the forces of good and evil—police, drug lords, and gangsters—locked in a three-way confrontation, an unprecedented anti-drug battle is set to unfold!
