CID officer Tong found himself caught in a dangerous web woven by a ruthless gang of killers hailing from mainland China. This sinister group targeted criminals, taking their lives and looting their ill-gotten gains, all under the guise of a twisted ideology that painted their actions as a form of protection for mainland China against the perceived scourge of Hong Kong's criminal underworld. As Tong delved deeper into this murky world of violence and deception, he realized that he was facing an enemy unlike any he had encountered before, one that operated with chilling efficiency and unwavering commitment to their twisted cause. Fueled by a dangerous cocktail of nationalism and criminality, the gang posed a threat not just to the streets of Hong Kong, but to the very fabric of justice and order in the region. Tong knew that he would have to tread carefully and think quickly if he were to unravel the mysteries surrounding this deadly alliance and bring the perpetrators to justice before more lives were lost in the name of their misguided crusade.
