Set eleven years after the events of The Terminator, it follows Sarah Connor, her 10-year-old son John, and a reprogrammed Terminator from the future as they defend themselves from a T-1000 and attempt to prevent Judgment Day, a future event in which machines will begin to exterminate humanity.

T2 was a significant box office and critical success. It had an impact on popular culture, and is considered by many to be hugely influential in the genres of action and science fiction. The film's visual effects include many breakthroughs in computer-generated effects, marking the first use of natural human motion for a CG character and the first computer-generated main character. The film won several awards including four Academy Awards for makeup, sound mixing, sound editing and visual effects.

Plot

In 1995, eleven years after the events of The Terminator, John Connor (Edward Furlong) is ten years old and living in Los Angeles with foster parents. His mother Sarah Connor (Linda Hamilton) had been preparing him throughout his childhood for his future role as the leader of the human Resistance against Skynet, but she was arrested after attempting to bomb a computer factory and remanded to a hospital for the criminally insane under the supervision of Dr. Silberman (Earl Boen). Skynet sends a new Terminator, a T-1000 (Robert Patrick), back in time to 1995 to kill John. A more advanced prototype than the Terminator that was sent after Sarah, the T-1000 is composed of "a mimetic polyalloy", a liquid metal that allows it to take the shape and appearance of anything it touches. Though it cannot mimic complex machines such as guns or bombs, it can shape parts of itself into knives and stabbing weapons and can mimic the voice and appearance of humans. It assumes the identity of a police officer and goes in pursuit of John. Meanwhile, the future John Connor has sent back a reprogrammed Terminator (Arnold Schwarzenegger), identical to the one that attacked Sarah, to protect his younger self.
