Sean Lau (Kwok) and rough-around-the-edges M.B. Lee (Leung) are uncomfortably sharing the position of acting police commissioner while their veteran superior is overseas. Strained relations reach the breaking point when emergency-squad commander M.Y. Shun (Joyce Cheng) and four of her team members are kidnapped. With his son Joe (Eddie Peng) among the hostages, and talk of a rat in the house, Lee assumes control of what ends up being a failed rescue. Supported by fellow top-brass buddy Vincent (Chin Ka-lok) and convincing Lee loyalist Albert (Lam Ka-tung) to back his actions, Lau steps in to call the shots… But has the entire hostage drama been an elaborate set-up?
This breathless, twisty Hong Kong cop thriller triumphed at the 32nd Hong Kong Film Awards, picking up nine statuettes including best film, best director, best screenplay and best actor (Tony Leung Ka Fai).
