Tong Fei (Nicolas Tse) is the young leader of the cops who are chasing a triad boss. Tong mistakenly kills one of the twin daughters of a prosecuting attorney who is trying the boss’ case. When the attorney’s other twin daughter is kidnapped, Tong takes the gamble to get her back. Screenwriter, Jack Ng, refuse to release their tense stranglehold on the audience while Nick Cheung embodies the hired kidnapper as a repellent, one-eyed killer-for-hire and turns it into a symphony of sympathy. The story builds its suspense through a variety of wonderfully staged action set pieces and a rhythmic, atmospheric score. Lam gets the adrenaline pumping with his energetic directing, which plays the humanity of the lead performances to full effect.
