1. The story originated from an ordinary traffic accident. The car of Luo Minsheng (Liu Qingyun), a famous Hong Kong securities company, was found to be bugged. According to police investigation, the bug was used for military purposes, and the security department was involved in the case. After Chief Inspector Jack Ho (Louis Koo) discovered that the eavesdropper was veteran Sima Nianzu (Daniel Wu), the police and robbers launched a series of chases, and suddenly smoke billowed.

2. Jack Ho thinks this is just a simple blackmail case. Unexpectedly, after in-depth investigation, he found a mysterious organization called "Landlord Association". It is said that this "landlord association" has dominated the rise and fall of the economic system for 30 years, and Luo Minsheng and Sima Nianzu are closely related to the "landlord association". Jack Ho was involved in it, and together with Luo Minsheng and Sima Nianzu, it set off a thrilling storm.
