Andrew Lau Wai-keung spins this third installment of the popular Young and Dangerous series to hit the theaters in a year. The film opens with the hero Ho-nam (Dior Cheng Yee-kin) run afoul of Crow (Roy Chueng Yiu-yeung), the psychotic henchmen of Tung Sing clan boss Camel Lok (Michael Chan Wai-man). When Tung Sing opens a club next to a bar run by Ho-nam's Hung Hing group, trouble soon ensues. While in Europe, Hung Hing boss Chiang (Simon Yam Tat-wah) gets whacked and Ho-nam gets blamed for the death. Meanwhile, Crow kills his boss and uses the funeral to kill anyone who might challenge his claim to power. Meanwhile, Ho-nam's friend, Chicken (Jordan Chan Siu-chun), is allowed to return to Hung Hing after a prolonged stint in Taiwan; Ho-nam's girlfriend, Smartie (Gigi Lai Chi), who was sent into a coma during the first movie, regains consciousness; and Chicken falls in love with foul-mouthed lass Shuk-fan (Karen Mok).
