Software expert Ray Brown is plunged into a life-or-death contest with PeaceMaker, a deadly artificial intelligence that has infected most of the world's computing devices. His determination to eliminate PeaceMaker leads him into a dangerous conflict with the Domain, a clandestine organization dedicated to a new world order. Humiliated by the federal government in an anti-trust trial that has torn apart her software company, CEO Dianne Morgan is obsessed with a plan to unleash PeaceMaker and shut down computer systems across the world. She is determined to crush the global economy unless the nations of the world agree to share power with the Domain. Although Dianne and Ray have never resolved a long simmering passion, she must hunt him down before he terminates PeaceMaker. As the Domain hunts Ray, Dianne learns of a mysterious third force that has discovered PeaceMaker and plans to attack the Domain. Dianne, Ray and this third force struggle for control, but PeaceMaker has its own plans.
