It's 20 years since Sentinel Prime was defeated, and the Autobots have been betrayed by the humans. The alliance has been terminated, the President being manipulated by two former Decepticons, El'Duga and Janeira, who have thrown the planet into chaos. Under their orders, the humans have started hunting down all of the Autobots and Decepticons, who have been forced into hiding as their only hope of survival. Meanwhile, a small group of Autobot and Decepticon survivors have been bringing their part of the war into Earth's solar system, currently warring on Saturn. They may be the only hope for the Autobots and Decepticons down on Earth, but they don't even know they exist. Will they be able to save them?
