As humanity picks up the pieces following the conclusion of “Transformers: Dark of the Moon,” Autobots and Decepticons have all but vanished from the face of the planet. However, a group of powerful, ingenious businessman and scientists attempt to learn from past Transformer incursions and push the boundaries of technology beyond what they can control — all the while as an ancient, powerful Transformer menace sets Earth in his crosshairs, forcing a mechanic and his family to join the Autobots as they are targeted by a bounty hunter from another world.
