Double Tap (2000)

Leslie Cheung stars as a psycho killer in this Hong Kong bullet fest. Nick (Cheung), a former shooting range champion who has been forced to drop his career due to injury, is persuaded to compete again by his girlfriend Colleen (Ruby Wong). Nick's comeback competition is interrupted by a suicidal lunatic, whom Nick duly dispatches with a bullet to the skull. Three years later, a trial witness and four policemen are found murdered, which leads several observers to the conclusion that Nick has become a psychotic killer. With his girlfriend in custody, our anti-hero goes into hiding, vowing to kill a cop a day until his beloved is released.
