Nearly a decade after occupation by an extraterrestrial force, the lives of a Chicago neighborhood on both sides of the conflict are explored. In a working-class Chicago neighborhood occupied by an alien force for nine years, increased surveillance and the restriction of civil rights have given rise to an authoritarian system -- and dissent among the populace.
As humanity picks up the pieces after the battle of Chicago, a shadowy group reveals itself in an attempt to control the direction of history…while an ancient, powerful new menace sets Earth in its crosshairs. With help from Cade Yeager, Optimus Prime and the Autobots rise to meet their most fearsome challenge yet.
