Five years after defeating Sentinel Prime and Megatron in Chicago, the Autobots have gone into hiding after the government deemed all Transformers as threats, and thus, began to hunt them all down. The government have thus replaced the Autobots with their own Transformers using technology from the fallen Transformers. For a reward, Texas mechanic Cade Yeager finds a truck that turns out to be the leader of the Autobots known as Optimus Prime. As the government hunts down all Transformers, Cade and his family are involved in the business between a bounty hunter and Optimus.—Kris S.
