Transformers: Age of Extinction has released an all-new international trailer full of never-before-seen footage from this Michael Bay directed summer sequel. A rare metal holds the key to human survival when the Decepticons return to earth to kill off the remaining Autobots, who have been in hiding since the events seen in 2011's Transformers: Dark of the Moon. Cade Yeager (Mark Wahlberg) and his daughter (Nicola Peltz) must team-up with Optimus Prime (Peter Cullen) to keep the world safe. Watch the humans join the battle as an intergalactic bounty hunter arrives to kill off Prime once and for all. Will a new army of Dinobots be able to restore peace to the galaxy?
