Terminator Salvation:
"Set in post-apocalyptic 2018, John Connor (Christian Bale), the man fated to be the leader of the human resistance against Skynet and its army of Terminators, and the future he was raised to believe in is altered in part by the appearance of Marcus Wright (Sam Worthington), a Terminator 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 find out a terrible secret that may lead to the possible annihilation of mankind."
