In the tragic battle of Chicago, although the Autobots successfully repelled the invasion of the Decepticons, they also caused the people of Earth to lose their due trust and respect. The "Tomb Wind" force formed by the CIA conducted indiscriminate hunting of all transformers. For a time, the Autobots and Decepticons disappeared from earth. One day, Cade Iger (Mark Wahlberg Marky Mark), a down-and-out mechanical inventor living in Texas, bought a dilapidated truck head. Unexpectedly, it turned out to be Optimus Prime, the dormant leader of the Autobots. The tomb wind troops that smelled the smell flocked to them. After awakening, Optimus Prime rescued the Cade family and also made contact with the Autobots scattered in various corners. On the other hand, crazy human scientists learned the secret of their transformation from the remains of Transformers and attempted to create artificial King Kong using this. The Stunning Sky, which was born from Megatron, is their favorite work and a death threat. A new round of crises is coming, and the earth is facing an even greater disaster...
