Breckinridge and Garrison try to figure out who might be the mole. As everyone who was polygraph tested showed up negative (except for Garrison), they review the list of those tested to see if there is anyone in the Secret Service who was not tested. The only name not on the list is that of the president's security director, William Montrose. Meanwhile, Montrose has been contacted by the leader of the assassins, who calls himself the Handler (Ritchie Coster), and informed that he must jam the communication radios as the President walks to his motorcade or his wife and children will be murdered. When Breckinridge and Garrison try to get into the summit building to warn the President about the impending assassination attempt, they are stopped by the security agents. Suddenly, all security radios go dead, and the agents don't know what to do. Inside the summit hall, Montrose suddenly leaps onto the podium and leads the President away. Breckinridge and Garrison race into the building, while the First Lady shouts The password is CRYSTAL!. Montrose leads the President through a series of corridors and stairways to get him to the safety of his motorcade, but the assassins follow and begin firing on them. Montrose tells the President to turn off his locater because that's how the assassins are tracking him. Breckinridge, Garrison, and other agents fire back at the assassins. One of them kills Montrose, and Garrison takes a bullet in his side. With Montrose dead and most of the other agents down, it falls on Breckinridge and Garrison to get the President to safety. When radios are again operable, Garrison contacts the motorcade and tells the security agent to get an armed guard to the southwest door in order to protect the President. When the President finally emerges, the guard surrounds and escorts him to his limo. Suddenly, one of the guards leaps forward and grabs the First Lady, holding her hostage. It is the Handler himself. Garrison aims and shoots him. The President is whisked away safely. In the final scene, Garrison has returned to the White House and is saying goodbye to the other SS agents. They give him a parting gift of a package of Depends. As Garrison walks across the North Lawn, the First Lady can be seen in a window watching him leave.
