Pike Logan and the Taskforce were once the apex predators, an unrivaled hunting machine that decimated those out to harm the United States, but they may have met their match. While Pike Logan and Jennifer Cahill prepare to join their team on a counter-terrorist mission in the triple frontier--the lawless tri-border region where Argentina, Brazil, and Paraguay meet--they are targeted in Charleston, South Carolina. A vicious explosion kills a friend, and the perpetrators have set it up to look like an accident. While the authorities believe this was not foul play, Pike knows the attack was meant for him.
