John Conner, now an adult, in fear of the events that took place at a young age, lives off the grid–no phone, no job, no credit cards. After failing twice, Skynet sends their most advanced machine to date, the T-X or Terminatrix, to not only kill John but his future wife as well.

Once again, a Terminator is sent to protect John and his future wife and has a small upgrade which allows it to mimic humans more. Not knowing how these terminators were sent, considering he thought he destroyed SkyNet, John will soon learn something that will change his life…forever.
