The civil war on Cybertron was in full swing. At the time of crisis, Optimus Prime sent the Hornet to the earth, waiting for the opportunity to re-establish the base. Since then, the bumblebee landed in California in 1987. Unexpectedly, it was not only first rounded up by the special agent Jack Burns (John Sena, John Cena), but also severely injured by the Decepticon members who came after it. It lost its voice and memory at the same time. On the other hand, Charley Watson (Hailee Steinfeld), a girl in the rebellious period, has been transformed into a bumblebee that has become a popular beetle by mistake. The two sides try to explore each other, and then become close friends. At the same time, they also make a lot of jokes. The good times are not long. Decepticon members smashed and rebounded to the earth. They first cheated the US government to find the trace of the bumblebee through the satellite network, and then tried to summon the Decepticon troops here. The bumblebee, who has gradually recovered its memory, is determined to protect its new friends and this beautiful blue planet by its own efforts
