Ging chaat goo si juk jaap
Inspector Chan Ka-kui has been demoted to highway patrol as the result of his handling of his previous case, which involved the violent arrest of crime lord Chu Tao and heavy property damage. The new duty pleases his girlfriend, May, who is glad that her boyfriend is no longer taking difficult cases and has more time to see her.
However, the happy mood changes when Ka-Kui is greeted by Chu Tao and his bespectacled right-hand man John Ko. It seems Chu Tao is terminally ill with only three months left to live, so he has been released from prison, and while he is still alive he vows to make life difficult for Ka-Kui. John Ko and some henchmen show up at Ka-Kui's apartment and intimidate him, baiting the policeman to attack. Later, May and her mother are beaten by John Ko and his men. Ka-Kui can no longer hold back, and he lashes out against John Ko and his men at a restaurant.
Ashamed of his behavior, Ka-Kui resigns from the Royal Hong Kong Police Force. He plans to take a trip to Bali with May, but while he is at a travel agency in a shopping mall, some police officers see him and report that the mall is under a bomb threat. Unable to resist the urge to get involved in police work, Ka-Kui tells the officers to sound the fire alarm and have the mall cleared, and agrees to take responsibility for the decision. A bomb does indeed explode, and the entire mall is leveled by the blast.
Ka-Kui is praised for his efforts, and he is reinstated and assigned to solve the case of the bombing. Ka-Kui plants a covert listening device in the mall property company's office to try to learn more about the bombers. This leads to a suspect who is a deaf-mute and is a fierce martial artist and explosives expert.
The bombing gang, aware that the police are on to them, plan a simultaneous bombing of the property company and the police headquarters. They double their ransom demand to $20 million and kidnap May, luring Ka-Kui into a trap in which he is strapped with an explosive vest and forced to pick up the extortion money from the property company. However, after picking up the money, Ka-Kui tells the gang that they are being followed and split up. Ka-kui, still holding the ransom, is able to drive his car into a tunnel so that the bomb he is wearing cannot be activated and he strips it off. He then goes to rescue May, who is being held in a warehouse full of fireworks. Ka-Kui again faces the deaf-mute man, who throws small firebombs at him. Ka-Kui then gains the upper hand and brutally retaliates against the mute man, finally throwing him off a third story catwalk onto a pile of plastic drums below. Ka-Kui then rescues May and departs the warehouse, just as it explodes in a huge ball of fire.
