The Terminator (1984)

In the year 2029, a computer called Skynet is fighting against a human resistance, after having nearly destroyed the rest of humanity in 1997.  A cyborg assassin called 'The Terminator' is sent back through time to 1984 to kill the seemingly innocent Sarah Connor-a woman whose unborn son will lead the human race to victory in a bitter future war with a race of machines. Kyle Reese, one of the soldiers in this war, has been sent back in time to stop the Terminator.
