When the home of Alex Cross's longtime friend Ellie Cox is turned into the worst murder scene Alex has ever seen, he is devastated. The destruction leads him to believe that he's chasing a horrible new breed of killer. As Alex and his girlfriend Brianna Stone begin the hunt for the villain responsible for the killings, they quickly find themselves entangled in the deadly Nigerian underworld of Washington, D.C. What they discover is shocking: a strongly organized gang of teenage thugs headed by a powerful, diabolical man—The Tiger. As the killing spree escalates, Alex and Brianna realize they are not dealing with any ordinary killer, but one who has brought his personal war of vengeance to America's capital. But just when the detectives think they're closing in on the elusive murderer, the Tiger disappears into thin air. Unable to let the killer get away with this narrow escape, Alex makes it his duty to bring the brutal butcher to justice. He knows that he must follow the Tiger. Alone. When Alex arrives in Nigeria, he discovers a world where justice is as foreign as he is. Unprotected and alone in a strange country, bombarded on all sides by the murderous threats of The Tiger, Alex must draw on his fiercest instincts just to survive in a lawless world.
