Choi is revealed as the mastermind behind the troubles of the previous film, and his current goal is to remove Lau, who is not a member of his ring, and to place his own followers into positions of power during the next election.

Kan and Lau report Lee's and Choi's crimes to the chief executive, who decides to grant pardon to both men since they are too important to arrest without destabilizing society.

Elsewhere, Lai continues his campaign to be elected as the future Chief Executive of Hong Kong, hoping to control the government's politics, leaving more mysteries unsolved.

At that time, co-director Sunny Luk also confirmed that the script for Cold War 2 was being written and was due to start production by the end of 2013.
