Tim (Sean Lau) is an ambitious Narcotics Bureau chief inspector who puts his career above all else. Chao (Louis Koo) embeds himself in the depths of Hong Kong`s drug circuit as an undercover cop and barely resembles his former self. Wai (Nick Cheung) is Tim`s loyal subordinate who hopes that one day he can gain others` respect through success. The three are life-long friends who would readily risk their lives for each other. But their new mission puts their brotherly bond to test. (gsc)
