Hong Kong stockbroker Manson Lowas involved in a car accident while driving to work. The accident attracted the attention of the anti-terrorism team after police identified a military eavesdropper in Lo’s car. The team leader Ho suspected that someone was planning a terrorist attack. Ho’s investigation revealed a hidden eavesdropper monitor, veteran Joe Sze-ma. Meanwhile, Lo told the senior leaders of “Landlord Society” that he was being eavesdropped on. This meant their crimes would be revealed. This seemingly regular blackmail case engulfed Lo, Ho, Sze-ma and many others into a doomed vortex.
