Set before the dawn of 2000, Laughing is an undercover cop whose current role sits right at the edge of a dangerous past in the triads, while Inspector Poon closes in with a determined pursuit to uncover the truth behind his facade. Laughing’s history as a triad member—and his ties to a powerful boss—shapes every move he makes and colors every choice he faces.
In the shadows of the underworld, Laughing once worked for the triad leader Brother One, Lai Tin-yat, a figure who treats him almost like an elder brother. To strengthen his criminal empire and protect its operations, [Brother One] arranges for Laughing to join the Police Force and become a mole, feeding him into the police ranks to gather intelligence on the plans and counter-plans as they unfold. This arrangement creates a web of loyalty and risk, where every secret Laughing uncovers could betray someone he’s still connected to.
Despite his checkered past, Laughing excels at the Police Academy, graduating with outstanding results. Yet before he can be posted to a steady beat, his “bad boy” image catches the eye of the Head of District Anti-Triad Squad, Superintendent Sin, who assigns him to undercover duty to infiltrate the very mob he once served. The assignment marks a new chapter: Laughing becomes a true double agent, treading a fine line between law and crime as he moves deeper into the triad world.
The undercover mission takes Laughing into the orbit of the rival triad led by Zatoi, a figure who makes life increasingly difficult as Laughing tries to stay one step ahead. The tension isn’t only professional; it becomes personal when Laughing falls for Karen, Zatoi’s sister, a connection that introduces a dangerous, undeniable pull between love and loyalty.
As the story unfolds, Laughing must navigate a maze of loyalties—the rigid code of the triad brotherhood, the duty of the law, and a fragile romance that could derail everything he has worked for. No matter which side he leans toward, a betrayal seems almost inevitable, and the path he ultimately chooses will determine where his true allegiance lies. The tale asks a stark question: which path will Laughing ultimately follow, and at what cost to the people he cares about and the life he’s built?
