Linebacker Riley Covington returns to another season of mini-camp for the Colorado Mustangs just as a wave of terrorist attacks begin to occur across the country. Sleeper cells are being awakened-likely by the leader of the Cause, who has recently escaped from captivity and is coordinating attacks not only on America but also on Riley and his loved ones. As Jim Hicks, Scott Ross, and the rest of the Counterterrorism Division follow leads in Europe, Riley goes on the offensive to draw out his attackers. But can the Cause be stopped before they're able to reach their ultimate goal?
