This is the story of three people (a police officer, a lawyer, and a murderer) who cross paths in the wake of the murder of a federal witness and the kidnapping of a pop star. CID Suen Siu-yang (Aaron Kwok) arrested the money launderer's accountant. However, the accountant is assassinated when he arrives at the Hong Kong airport. The murderer Koch (Daniel Wu) escapes without leaving any clues behind him. The ringleader, a laundry shop owner (Galen Roe), is happy that his assets, which were frozen due to the death of a damaging witness, will soon be reopened, but his beloved son Thea is suddenly kidnapped. Suen is an unlucky CID. He can't forget his beloved girlfriend (Angelica Lee), who disappeared 10 years ago and has never been found. During his investigation, he discovers a woman (Angelica Lee) who looks a lot like his missing girlfriend. The woman is the wife of To (Ekin Cheng), a lawyer who is the representative of a cleaning company. It increases his interest in the couple. Murderer Cork has completed his mission, but he can't help but take great interest in this case, which violates the Murderer's Code. He does this because years ago Suen was the host of a police call and it made a big impression on him. And he knows why Suen's girlfriend disappeared 10 years ago. Attorney Toh is very successful in his field. He always wins in court and helps suspects avoid prison sentences. Is there a hidden side to an arrogant person like him? The characters in the story all seem to have some quality that doesn't fit their individual identities. Will it drag them into the vortex? At the same time, many other crimes are occurring in the city. Murder cases and disappearances with unknown motives are occurring frequently. Is the incident related to the three characters in the story?
