寒战2 Cold War 2

“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 郭富城) gains him promotion to the highest rank in the police force, yet causes Deputy Police Commissioner M.B. Lee (Tony Leung Ka Fai 梁家辉) his reputable career. Joe Lee (Eddie Peng 彭于晏), 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 周润发), an influential senior counsel and 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 master plan into play.

李家俊在同伙的协助下成功逃脱，而刘杰辉也由于违反警队规定擅自行动，遭遇香港立法会质询。立法会遂召开调查委员会进行聆讯，委员会其中包括了资深大律师简奥伟 (周润发饰）。他是敌是友，没人晓得。这时，一直隐藏在背后真正的始作俑者开始执行大计划，香港也将面临更大的危机...
