The terminator (Anorld Schwarzenegger) has returned and this time he has a new mission and that is to protect the leader of the human-led resistance against the machines, John Connor (Edward Furlong) son of Sarah Connor (Linda Hamilton) who was first targeted. The terminator was sent by John Connor himself in the year 2029, and as a result has to obey his orders and protect him (as a child) from the more advanced T-1000 (Robert Patrick), which is a shape-shifting liquid metal terminator which has been sent by the Skynet computer to pick up from where the first one had left off.
