As one of the world's leading authorities on technology, Malcolm Fitzpatrick uses his expertise to identify a unique brand of criminal: the privileged killer. These über-successful men sacrifice innocent lives in their pursuit of wealth, power, and greatness. Alarmed by their growing presence in Europe and the courts’ unwillingness to hold them accountable, Malcolm decides to intervene personally.

In Paris, meanwhile, investigative journalist Camille Chevalier has written an incendiary story detailing despicable acts committed by three prominent Parisians. Before it goes to press, however, her editor leaks the story to one of the perpetrators, placing her life in imminent danger. To survive, Camille goes underground where she encounters an unlikely benefactor, Malcolm.

Together they devise a plan to ensure the men identified in her story never harm anyone again. The ensuing cat-and-mouse chase crisscrosses Europe through Monte Carlo, Cannes, Geneva, and, finally, Paris, where an explosive, nail-biting finale occurs.
