At the end of Terminator 2: Judgment Day, Sarah, John, and the
Terminator successfully destroy the T-1000 and the arm and computer
chip from the first Terminator. Sarah and John then watch as the
Terminator is lowered into a molten steel pit in an attempt to
destroy all future technology that could be used to create Skynet.
Sarah and John now find themselves alone in a very dangerous and
complicated world. Fugitives from the law, they are confronted with
the reality that still more enemies -- from the future and the
present -- could attack at any moment.
Prompted by the return of the Terminators into their lives, Sarah
and John decide to stop running and focus on stopping the birth of
Skynet. They are aided by Cameron, a Terminator who poses as a
student at John's school and whose mission is to protect John.
Meanwhile, FBI Agent James Ellison pursues Sarah and John with the
belief that Sarah is deranged.[21][22]
An advanced script review by TV Squad revealed that time travel
will play a major role in the series premiere including a temporal
leap for the main characters from 1998 to 2006.[23] (The pilot
episode as broadcast takes place in 1999 with a jump to 2007.)
Three video clips from the upcoming series premiere published on
the IGN website included the evil Terminator using Sarah's voice
over the phone to find John, Sarah and John fighting over their
current situation, and the evil Terminator looking for John, Sarah,
and Cameron at the Dyson residence
