Lau Kar-leung directs this action-comedy yarn about lazy police veteran Francis Li (Chow Yun-fat) and his eager beaver partner Michael Cho (Conan Lee Yeun-ba). The two are assigned to investigate the murder of a drug dealer who was known to be associated with crime boss Johnny Law (Norman Tsui Siu-keung). The duo interrogate comely bar girl Marydonna (Nina Li Chi) who is the sister of "Poison Snake" Ping (Phillip Ko Fei), one of Law's associates. Marydonna eventually caves under the intense pressure and fingers Law. Though the criminal soon winds up in the clink and Li gets his long overdue promotion, Law is hell-bent on revenge. Gun fights, explosions, and a wild and woolly duel with chainsaws ensues.
