Set during the year of 2018 after a nuclear war started by Skynet, a self-aware computer programm, mankind is on the brink of extinction. Salvation lies with the human resistance, and one man in particular; John Connor (Christian Bale). John Connor feels as though he understands and knows his robotic enemies, but this radically changes when he encounters Marcus Wright ( Sam Worthington). Marcus believes he is completely human, but Connor discovers there is more to Marcus then he realizes. Marcus tries to earn Connors trust by informing him the location of Kyle Reese (Anton Yelchin), an important character in the future of the survival of the human race. This leads Connor and Marcus on a journey into the heart of the machine operation and possible extinction. Not only of the resistance, but of the entire human race.
