With T'Pol and Trip hostage, John Frederick Paxton demands that all aliens leave the solar system or else he will destroy Starfleet Headquarters. With that warning and the clock counting, Starfleet orders Archer and the Enterprise to Mars to take out the weapon threatening Earth. Meanwhile, the cloned baby of T'Pol and Trip is getting sicker and time is running out for her as well. Imprisoned, Gannet Brooks reveals to Travis that she is a secret member of Starfleet Intelligence. She has been assigned to find a Terra Prime operative working undercover on the Enterprise. With the clock ticking, the future of the planned Federation lies in the balance. Written by timdalton007

An exciting conclusion.
10 June 2015 | by (Bradenton, Florida) – See all my reviews

This is the penultimate episode of "Star Trek: Enterprise" and it does a great job of setting the stage for the ending of the series. In it, Enterprise must sneak into the compound on Mars of the nut-case (Peter Weller) who is threatening to destroy the Federation before it can begin. In other words, while the humans and their new alien friends are about to sign a treaty forming the Federation, this idiot plans on destroying all this due to his xenophobic dream!

Part two focuses on the infiltration of the compound and then setting the wheels in motion for the Federation. Each was accomplished well and in an exciting fashion. Because of this, it makes a fine addition to the Trek franchise--well worth seeing and Weller makes an excellent baddie.
