Here is a mole in the police waging a war on crime, tipping off a criminal gang. Then, why the mole communicates secretly with the gang? What is their purpose? <Cold War> talks about a story different from other typical crime films in the course of uncovering the inner enemy. It is difficult for the audience to predict what is the purpose of the mole and this is how <Cold War> announces the arrival of a new type of crime film made by young blood. Five Hong Kong police officers are kidnapped. As the chief of Police Affairs is on business trip, two deputy chiefs, Sean Lau and M.B. Lee, set out to solve the case. They are in competition for the chief position and distrust each other. Lee first takes charge of the case as the acting chief but comes to a dead end. Lau, who then takes over the case, falls prey to a plot. The two end up being under ICAC (Independent Commission Against Corruption) investigation. Although the case is solved after many twists and turns, war on crime still goes on. This film highlights the rivalry between Lau and Lee in the process of solving the case or how the case about external war is influenced by internal conflict. It is related to overconfidence, thirst for fame, and lust for power. In other words, this film closely looks into the conflict between human innate desire and conscience rather than the rivalry between good and evil. That is why <Cold War> is a well thought-out crime film and, at the same time, an excellent psychological film. (KIM Ji-Seok)
