Transformers: Age of Extinction movie plot

In the tragic Chicago War, although the Autobots successfully repelled the invasion of the Decepticons, they also caused the people on earth to lose their trust and respect. The Tombwind Force organized by the CIA carried out an indiscriminate hunt for all Transformers. For a time, the Autobots and Decepticons were all gone on the earth. One day, Ced Eagle, a down-and-out mechanical inventor living in Texas, bought back a dilapidated truck front. Who knew it was the dormant Autobot leader, Qingtian column. Smelling the tomb wind troops swarmed in. After awakening, Optimus Prime rescued the Cade family and got in touch with the Autobots scattered in every corner. On the other hand, crazy human scientists learned the secret of their transformation from the remains of Transformers, and attempted to use this to create artificial King Kong, and the Jingpotian born out of Megatron is their proud work and a reminder of death. A new round of crisis is coming, and the earth is facing even greater disasters.
