Human Resistance leader John Connor launches a final offensive against Skynet, an artificial general intelligence system in 2029. Before the Resistance can triumph, Skynet activates a time machine and sends a T-800 (Model 101) Terminator back to May 12, 1984, to kill John's mother Sarah. John's right-hand man, Kyle Reese, volunteers to travel back in time to protect her. As Kyle floats in the machine's magnetic field, he sees John being attacked by another Resistance soldier and has visions from his childhood about Sarah Connor. When it arrives in Los Angeles 1984, Skynet's T-800 is disabled by Sarah and 'Pops', a reprogrammed T-800 sent to protect Sarah when she was nine years old. Kyle arrives shortly afterwards, and is intercepted by a T-1000. Sarah and Pops join Kyle and destroy the T-1000 with acid; she and Pops reveal that they have constructed a makeshift time machine similar to Skynet's, and Sarah plans to travel to 1997 (the year Skynet becomes self-aware). Realizing that the time-line has been altered, Kyle is convinced that the future has changed because of the warning he received in his childhood vision and persuades Sarah to travel to 2017 to stop Skynet..
