 Terra Prime terrorist John Frederick Paxton sets an ultimatum. He will destroy Starfleet Headquarters if all aliens do not depart from Earth. Paxton s action has a devastating effect on the alliance conference. Seeing the divided nature of humans, Andorians and Vulcans refuse to negotiate any further. On Mars Paxton agrees to let T Pol and Trip see the child, but then forces Trip to fix the targeting system of the array. He refuses to cooperate, but by doing so he risks more lives getting lost on Earth. Meanwhile the crew of Enterprise think of a plan to shut down the array. Approaching the deathly station undetected is only possible with a shuttle pod hidden inside a comet. Then the imprisoned Gannett Brooks has a message for Travis, the pilot of the shuttle pod. She tells she is a secret member of Starfleet Intelligence and is afraid a Terra Prime operative will know about the plan.
