When a police raid seize his supplies of illegal arms, a crime lord known as "The Lion" (Simon) decides to get even by sending out his most trusted lieutenants, Panther and Wild Cat, to eliminate the members of the police force responsible for the mission. Among the personnel involved in the mission is Inspector "Rose" Wang (Moon) and her cousin "Orchid" (Wong Yee-Kam note ), who must team up with FBI agent Stephen (Max) sent from the United States to assist the Hong Kong police to take down the Lion.
Mission Kills always seems to linger around in 3rd gear and never shifts into higher gears, well not till the end which features some wild action. Everything seems so sluggish. An okay movie, though, mainly because of the cute Moon Lee, who is on top form, kicking behind with abandonment. Simon Yam is cool as a villain who doesn't like his henchmen failing in their mission and even slices a finger off one girl, Fujimi Nadeki and Ken Lo are good as a killer couple in the service of Simon Yam.
