Action flick auteur Ringo Lam directs this crime thriller loosely based on Peter Weirs 1985 classic Witness. Lau (Chow Yun-fat), along with his partner, Nam (Tommy Wong Kwang-leung), are investigating a band of gun runners when they get caught in a shoot out that kills their lead suspect and leaves the suspects three-yea-old daughter Ka-ka parentless. Lau eventually tracks down the childs family in a remote country farm in Hong Kongs New Territories run by Cher (Cherie Cheung Cho-hung). Though initially the two loath each other, soon they start to warm to one another. Cher tells him that Ka-ka is the illegitimate child of crime boss Hung (Paul Chun Pui). When Lau confronts Hung, the cop promptly gets his clock cleaned and psychotic Vietnamese gangster Bullet (Roy Cheung Yiu-yueng) is sent out to whack him. Bullets first attempt goes poorly, resulting in a trashed bar and a wounded hit man. Bullet vows bloody revenge. Meanwhile, Chers thuggish husband Leong returns from mainland China about the same time that Bullet is about to stage a second attack. ~ Jonathan Crow, All Movie Guide
