Detective Alex Cross is planning his wedding to the woman he loves, Brianna Stone. But this blissful existence begins to unravel when Cross is called to the scene of the perfectly executed assassination of two of Washington DC’s most corrupt and publically hated political figures. As more crooked politicians are picked off with similar long-range shots, public opinion is divided – is the marksman a vigilante or a hero?
Media coverage of the case explodes, and the FBI assigns agent Max Siegel to the investigation. As Cross and Siegel battle over jurisdiction, Alex receives a call from his deadliest adversary, Kyle Craig. The Mastermind is in DC and will not stop until he has eliminated Cross, and his family, for good.
