Was it a case of mistaken identity or was Billy Mack deliberately chosen? On a business trip to Vienna, Mack is taking a break from heated negotiations when a beautiful, mystifying woman sits at his table, addresses him by name and acts as if they were lovers. When he discovers what she slipped into his pocket, he is dragged into a terror plot designed to start the next world war and begin the worldwide Caliphate. With his life on the line, he is stuck in a Catch-22 world of espionage, deception, terror and murder. He must stay one step ahead of the terrorists while chasing after them to stop their devastating attack. In a world where human life is used and easily discarded, the terrorist made a wrong move and Mack has one chance to make them pay. As he goes on the attack, he must figure out whom he can trust. When he's at his most vulnerable, he finds a guardian angel ... or did the guardian angel find him?
