Set in post-apocalyptic 2018, John Connor is the man fated to lead the human resistance against Skynet and its army of Terminators. But the future Connor was raised to believe in is altered in part by the appearance of Marcus Wright, a stranger whose last memory is of being on death row. Connor must decide whether Marcus has been sent from the future, or rescued from the past. As Skynet prepares its final onslaught, Connor and Marcus both embark on an odyssey that takes them into the heart of Skynet’s operations, where they uncover the terrible secret behind the possible annihilation of mankind.
Connor does not start as leader of the resistance but will work his way through the ranks in the film. He is also mistrusted by other soldiers due to his extensive knowledge of Skynet. McG said that it will be about the development of the Model 101 Terminator as well: scenes involve humans being captured and studied by Skynet in order to perfect their cybernetic organisms and Connor explaining “If we let these things go online, the war is over.”He explained the film will “begin again very much in the spirit of what Nolan did with Batman,” in that it will not require audiences to have seen the previous films, and that it is “a bit of a sequel and a prequel because it tells the story of how we got there.
