The advance force of the "Decepticons" attacked the U.S. military base in Qatar. At the same time, the roadblock helped his partner sneak into the U.S. President's landline Air One. It was learned through the computer that if you want to find Megatron, you must find the Witwich family's glasses, which contain Megatron's information about the energy block, and its current owner, Sam Witwich (Shian Labouf), has become the target of the "Decepticons" attack. Sam was a high school student, and no one in the school believed his story about the history of the glasses. Disappointed, Sam put the glasses on the Internet for auction, but never attracted the interest of buyers. At this time, his father gave him a broken car, which happened to be a variant of the "Autobot" Hornet. Bumblebee helps Sam make a beautiful girlfriend (Megan Fox), but is soon attacked by the Decepticons. Optimus Prime arrives with other "Autobots", and a robot war begins.
