When a spike in CIA intelligence suggests a major terrorist attack planned for Memorial Day, the president orders Mitch Rapp, his top counterterrorism operative, to pull out all the stops. Rapp immediately leaves for Afghanistan where he leads the ultra secret counterterrorism Special Forces unit on a daring commando raid across the border into Northern Pakistan. Their target: an al-Qaeda stronghold. Within a subterranean room, Rapp and his team discover a treasure trove of maps, computers, files and bills of lading for multiple freighters heading to US ports - all pointing to plans for a catastrophic attack on Washington DC. Information is quickly relayed back to CIA headquarters, and a nuclear emergency search team scrambles to the scene.
