On the eve of the election of Hong Kong's chief executive, a well-planned "judicial frame-up" made Police Commissioner Liu Jiehui a prisoner. Former Deputy Commissioner Li Wenbin discovered that there was a bigger conspiracy hidden in the death of his son. As the investigation deepened, a cross-class group called the "Shadow Collegiate Chamber" emerged - they are not terrorists, but "system architects" who aim to use the crisis to promote the Special Security Ordinance and permanently reshape Hong Kong's governance rules.
Security Chief Lu Minghua and Councilor Jane Ouwei were forced into the whirlpool. All parties made difficult choices between legal procedures and extraordinary measures. The truth finally revealed is extremely cruel: all the bloodshed and sacrifices in Cold War Parts 1 and 2 were actually the "stress test" of this power experiment. When the means to protect the system continue to tarnish the system, who can still represent justice? This is a war without heroes, only the ruthless devouring and reconstruction of human nature by the system.
