The White House gets word that CTU lost contact with Jack. They watch as another hostage is shot in front of the camera. Beresch accuses Logan of signing a "corrupt" treaty with the blood of hostages. The President is horrified, and he offers to postpone the summit in order to save the people. Cummings advises Logan to stay on course because the terrorists will never release the hostages.

Jack hesitates and then finally gives Curtis the green light to move in. Curtis counts down a minute to launch, not knowing that bombs are set up where his men are about to enter.
McGill rushes into the CTU situation room and demands that the assault be stopped. He found that Jack was using a code to indicate that an agent is making a communication under duress. Although nothing came up on the filters, McGill points out that "flank two" was the code back when Jack was an active agent. Chloe confirms this, and Buchanan tells Curtis to abort and go back to the original set up.
Beresch doesn't understand why CTU is late in attacking. He makes Jack call CTU, and Buchanan tells Jack that there was a malfunction. They will be ready to launch the attack any minute.

As soon as the treaty is signed, Martha urgently requests a few minutes alone with Logan. He promises to speak to her after the ceremony. She demands to be paid attention to, exclaiming that she is not crying wolf. "Do not ruin this moment for me," Logan dismisses. Cummings approaches the distraught Martha, who helplessly says that the situation is more dangerous than the President knows. Cummings presses her for information, but she will only talk to her husband.
Buchanan apologizes to McGill for brushing him aside because his thoroughness helped save the day. McGill asserts that it was Buchanan's insistence about Jack's integrity caused him to double check. Yet McGill still wants Jack taken into custody because he hasn't been fully cleared of Palmer and Michelle's deaths. Audrey pipes in that the evidence and Chloe's testimony prove that he is innocent, but McGill notes that the video surveillance of Jack near the assassination site was not doctored.
