A skirmish in the desert on the Texas/Mexico border set events in motion that put Alan Ramsey, a prior Special Operations Captain turned terrorism subject matter expert, and his newly recruited partner, Paul Jackson, on high alert as they follow a criminal pattern that indicates the immediate war on terror isn't exactly over. When it is suspected that a nuclear warhead has made it onto American soil and is in the hands of a group of terrorists led by a ruthless Iraqi insurgent, Leaja bin-Masri, the stage is set for a race against time to stop the terrorists before the weapon can be deployed. With Alan Ramsey's team on the heels of the terrorists at every turn, bin-Masri must decide to keep moving or use the weapon before reaching its destination, taking the CIA, FBI, and the local police on a wild ride down several different and sometimes simultaneous paths in a final act of defense that culminates with a heart pounding, white knuckle ride to beat the clock.
