The film takes place in our days, well, not quite, somewhere in the early nineties. Cyborg T-101 appears again on Earth, but not to kill and destroy. New its purpose is to protect the son of Sarah Connor — John. And that John Connor from the future has collected and reprogrammed the cyborg to send in the past. During the film, the future leader of the world resistance, an ordinary American teenager living in foster care. And his mother, usual, or not quite the usual "crazy", languishing in a psychiatric hospital. Enemy of Schwarzenegger in this picture stands, no longer a man, but also a cyborg, only much more advanced, able to take any number of forms and types. Oh Yes, and practically invulnerable.
