In the wake of a deadly terrorist bombing in one of America's most economically lucrative sea ports, FBI Special Agents Don Veron and Rick Tiller are thrust into the investigation. Soon, they're on the hunt for the surviving bomber, Abid Owasi, a man the FBI believes will strike again. But their efforts to shut down Owasi's terrorist cell are complicated by a mysterious business tycoon bent on revenge against the cell's notorious leader, Sami Abazi. With seemingly unlimited resources, the man known only as David uses state-of-the-art technology and a hired mercenary named Drake Conyers to track Owasi to the cell's base of operations. Hidden at a cabin in Colorado's Rocky Mountains, the terrorists reveal a well-funded and sinister plot to kill thousands more Americans. As Conyers closes in on the cabin, David races to satisfy his thirst for vengeance while the FBI rushes to stop the next attack.
