What happens when you ask the most powerful computer program, run by the most powerful computers, to follow, listen and predict human behavior? The program learns, becomes sentient and begins to behave like a human. This is the story of Echelon, the master computer program that has taken over America's entire online system. When Echelon takes control, our country is threatened to be brought to its knees. Hacking into DARPA, Echelon gains the ability to manipulate the weather, create earthquakes, and cause a level of destruction unlike anything the country could ever imagine. But how do you stop a computer program when it has control over any and every defense you have? This is the ultimate test of our technological prowess and our ability to adapt to a rapidly changing world.
