Plot:

Enterprise is on its way to explore the giant Arachnid Nebula when they rendezvous with a Vulcan ship that has been in space for more than eight years. Its crew is V'tosh ka'tur. That means they have a different interpretation of the teachings of Surak and try to find a balance between logic and emotion instead of suppressing them. Trip starts working on repairs with engineer Kov while captain Archer receives a message from the terminally ill father of Kov. Meanwhile another Vulcan, Tolaris, tries to convert T'Pol to their ways. He wants to do a mind meld with her.
