In the final act of the Infernal Affairs trilogy, corrupt cop Lau is reinstated to Internal Affairs as a senior inspector, but is threatened by another cop tasked with exposing moles from the deadly triad gang. Suspicions within the police force and the triads rise to a lethal boiling point, culminating in an explosive showdown that brings this landmark saga to its shattering conclusion.
