The hero fought and helped people. A girl named Charlie, working as an auto mechanic in one of the garages, discovers a very damaged but pretty Volkswagen Beetle on a California landfill. It was there that he found the asylum of Bumblebee, who had received battle wounds and had fled. The girl will return the car to life, realizing in the course of the repair, that in front of her - a transformer. Charlie will start to help Bumblebee, and he will find a true friend in her face.
