On the night of the President's speech, Breckinridge and Garrison race to the summit. The assassins, posing as Royal Canadian Mounted Police Emergency Response Team officers, kill several agents and corner Montrose and the President in a tunnel. Montrose reveals his treason to the President and purposely steps in front of one of the assassins, who kills him. Garrison, Breckinridge and Marin arrive, rescuing the President and the First Lady and killing the assassins. As they reach the ground level, Montrose's handler comes forward dressed as an RCMP officer to personally perform the killings. He takes Sarah hostage and aims his pistol at the President, but Garrison shoots him dead. In spite of these events, Garrison is forced to take an early retirement due to the disclosure of his affair with the first lady, who looks on sadly from her window as Garrison leaves the White House. He does, however, make peace with Breckinridge, who finally realizes that Garrison did not sleep with his wife. Breckinridge tells Garrison that he has a date with her that evening.
