Synopsis
“Cold War”, the codename for the rescue operation of the five kidnapped police officers, is deemed a partial success. Despite the political outcry, the risky rescue led by Acting Police Commissioner Sean Lau (Aaron Kwok) gains him promotion to the highest rank in the police force, yet causes Deputy Police Commissioner M.B. Lee (Tony Leung Ka Fai) his reputable career. Joe Lee (Eddie Peng), son of M.B. and the sole suspect of the kidnapping, is captured and taken into custody. The case remains an unsolved mystery, and Sean is hell-bent on uncovering the details.
Sean’s family gets in crossfire, forcing him to make the toughest decision of his life: exchange Joe’s freedom for his family’s safety. With his career now on the line, Sean faces an impeachment proceeding that includes Oswald Kan (Chow Yun Fat), an influential senior counsel and an independent member of the judicial council. He becomes the key figure in determining Sean’s fate, and it is unknown whether he is friend or foe. Sean’s adversaries within the police force, in an attempt to bring down his career, are desperate to get Oswald on their side. With enemies moving from the street and into the political arena, the real kingpin, who’s been lurking in the dark all along, is slowly bringing his masterplan into play.
