Disgraced former Presidential guard Mike Banning finds himself trapped within the White House following a devastating and well-coordinated terrorist attack. The assailants, a North Korean-led guerilla force, have taken the President and his key staff hostage in the impregnable presidential bunker while a national security team scrambles to respond. With the Vice President and the Secretary of Defense held in a secure location away from the chaos, communication lines are cut, and the White House is transformed into a no-man's land.

Banning, with his intimate knowledge of the presidential residence, becomes the eyes and ears of Acting President Allan Trumbull and the national security team. As the terrorists initiate their demands, Banning navigates the besieged corridors, engaging in deadly combat, and becomes the country’s only hope to rescue the President, prevent the execution of hostages, and avert an even larger catastrophe that looms on the horizon.
