Plot
Three years after the events of The Last Knight, the Autobots were fighting a losing battle to protect their home planet of Cybertron from being devoured by Unicron, who actually is planet Earth the whole time and also endangering all humankind. Out of options, the Autobots enlist their human friends Cade, Viviane, Lennox, Simmons, Izabella, and Sam to travel back in 1988, one year after the events of Bumblebee, and team up with their past selves to stop Unicron from ever being reactivated. Little do they know that the Decepticons, with Quintessa helping them, are in pursuit and teaming with their past selves as well.
