Transformers: Age of Extinction Trailer 2

Four years after the catastrophic events in Chicago, Earth has mostly recovered from the great war between the Autobots and the Decepticons. But when Cade Yeager (Mark Wahlberg), a struggling inventor, and his daughter Tessa (Nicola Peltz) discover Optimus Prime, they bring down Decepticons, Autobots and the US government on them. Now with the Decepticons plotting to destroy the Earth once again, and a paranoid government official (Kelsey Grammer) on his tail, Cade must join the Autobots, and Optimus Prime must align with the ancient Dinobots, to save Earth from extinction.
