Synopsis

By a strange twist of fate, dutiful Hong Kong policeman Dan saves the life of the leader of a violent gang of armed robbers. When they commit another crime, Dan is determined to put an end to their activities. He works with the leader, whom the gang had betrayed, to engineer a plan to wreak havoc within the gang and let the gangsters kill one another. But it becomes increasingly obvious to Dan and to his colleagues that Dan is suffering from a severe mental disorder, and Dan finds that instead of upholding the law as a righteous police officer, he has now become a fugitive wanted for murder.

Plot

Reclusive cop Dave Wong (Daniel Wu) unwittingly saves the life of criminal gang leader Hon Kong (Nick Cheung) by donating his blood to him. The gang members hide their faces behind traditional demon masks when committing their violent crimes. During psychotic episodes, Dave experiences his own demons within as he sets out to play off the gang members against each other, resulting in everyone's annihilation. It is then revealed that Dave was brought up by a high expressed emotion father in a socio-economically disadvantaged living environment. He witnessed his father's death inadvertently caused by the responsible policeman who resembled Hon Kong. As a young, innocent soul who had lost his father, he impulsively went on to take revenge, resulting in excessive guilt that predisposed the onset of psychosis later in his life. The event whereby he rescued Hon Kong reminded him of his suppressed memories as a child who had done wrong but trying the hardest to make reparation. Before his inevitable death, there was an opportunity for him to resolve his subconscious intrapersonal conflicts which was to have the courage to fix a mistake done.
