Jack is arrested, and Burnett refuses the President's offer of immunity in exchange for the information regarding Juma's target. Meanwhile, Dubaku is discreetly murdered at the hospital.

Renee is rescued by Larry and informs him of the attack as Juma begins his subterranean assault. Jack is released to help guard the President en route to the nearest safe room. Bill realizes that Juma is locating the President via her tracking bracelet; he takes it and leads Juma and his men away from the President so that Jack will have enough time to escort her to the safe room. Bill is consequently captured with the rest of the White House staff. Jack and President Taylor reach the safe room while the Secret Service and Marines close in on Juma's men. Juma bluffs by announcing he has the President, forcing the federal agents to withdraw and surround the White House. The Vice President refuses to authorize a rescue attempt, fearing political consequences for himself if the President dies because of his order. Juma finds Olivia and threatens to mutilate her, compelling the President and Jack to leave the safe room.
