Cheung coordinates with his handler, Superintendent Chow, and senior inspector Kong Yiu-wai of the Regional Crime Unit, and manages to arrest a number of Hung's underling, including his younger brother, Hung Kai-piu, after performing a cash vault robbery, and also successfully disposing of a bomb, stopping it from detonating.

Six months later, Cheung resumes his position in EOD and is quickly promoted as superintendent of the department and meets a recently divorced primary school teacher, Carmen, and begins to date her.

A year later, Hung has employed a group of mercenary soldiers, delivering morphine and heroin for drug dealers in the Golden Triangle.

The day after, Hung plants a bomb with a mercury trigger outside of the Revenue Tower, which Cheung successfully disposes, before bringing in three pounds of C4 via a remote control toy truck, which is set to detonate in three minutes, so Kong drives Cheung to toss the bomb into Victoria Harbour.

As Blasts sets off the timer to go off in two minutes, Cheung is unable to disable the bomb and Wong is killed by the explosion, devastating several police officers and the press at the scene.

The next morning, the blocked Western and Eastern Harbour Crossing has been opened for the public which strict security checks while Yim is making a fortune when Man Cheung's stocks skyrocket and pays him a commission of HK$500 million.

In the meantime, Blast also captured Carmen and tied her inside the trunk of a taxi with a grenade in her hand, but Cheung finds and rescues her at a gas station.

Cheung then wears some C4 explosives around him and enters the tunnel, threatening Blast to hand out the remote for the 1,000 kg of C4, which startles a couple of the mercenaries and ignites a gunfight where Cheung shoots Blast's leg, while Kong's squad and the Special Duties Unit rush in and takes down the mercenaries while evacuating the civilians, where Kai-piu and a some officers and hostages were killed.
