Plots

A machine from a post-apocalyptic future travels back in time to protect a man and a woman from an advanced robotic assassin to ensure they both survive a nuclear attack. - vsuperkuns

More than 10 years after 'Terminator 2', John Connor now exists only as a drifter - living 'off the grid', so no more Terminators from the future can hunt him down. Unfortunately, SkyNet does send another one back - and this one is called the T-X, even more powerful & advanced than the dreaded T-1000. However, another CSM-101 Terminator is also sent back to protect John against the T-X. Now, Skynet is patiently assuming control of civilian computer systems, under the guise of a computer virus. John has also met his future wife, Kate Brewster, whose father - a U.S. Air Force General - is in charge of the military computer systems & is leery of up linking SkyNet. However, when the SkyNet virus infects the U.S military computers & leaves the country open to attack, the machines begin their horrific takeover. Soon a nuclear war will result - and the war against the machines will begin. Can the outdated CSM-101 Terminator eliminate the highly advanced T-X - or will a darker future await man following the nuclear attack? - Derek O'Cain

Living off-grid--ten long and challenging years after the encounter with the liquid-metal killer in Terminator 2: Judgment Day (1991)--the resilient survivor and now-23-year-old vagabond, John Connor, knows that these are dark and uncertain times. For the third time, the self-aware computer network, Skynet, sends another cyborg assassin--this time, its most efficient and technologically perfect model, the gynoid-like T-X--to terminate the future leader of the humans; however, the Resistance, too, has sent a protector: the reprogrammed but long-obsolete, T-101. Once more, the future is hanging by a thread, and this time, it's either us or the cold robots. Is humankind prepared for the Rise of the Machines? - Terminator 2: Judgment Day (1991)

It is a dark time for the resistance and Skynet is on the verge of going online, the events of the last movie has changed nothing and John must now battle a new Terminator called the T-X. As before, the resistance was able to send another T-800 as a protector for John, and its still a question of which one will reach him first... - Scott

On the verge of Judgement Day, the most advanced Terminator unit ever, the T-X, arrives from the future to ensure the rise of the machines. The only hope against it is a new upgraded T-800 unit, the T-850, that is sent back by the human resistance. Together with John Connor, it must stop the rise of the machines or all humanity will fall. - Paul McLaughlin

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 mimick 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. - Hayden
