x-Zane

Jun (Yen) is the kind of cop who always gets his man, but may set a whole city block ablaze in the process. Though his superiors are constantly on his case, Jun knows how to get the job done and never hesitates to innovate in times of crisis. Archer (Lui Leung-wai), Tony (Collin Chou), and Tiger (Yu Xing) are three dope slingers who supply the product for much of the local drug trade, and Jun is determined to take them down at all costs. Assisting Jun in his task is undercover cop Wilson (Louis Koo), a seasoned veteran capable of infiltrating the gang and gaining their trust. Though Wilson is at first successful in his mission, his cover is soon blown and a fierce battle leaves him unable to walk on his own. Fortunately for the good guys, Archer is captured in the violent fracas. While at first this seems like a major coup for law enforcement, the small victory takes a grim turn when vengeful brother Tiger vows to eliminate sole witness Wilson before the case ever goes to trial.
