While debating the ethical dilemma of an auto parts store with Optimus Prime and Bumblebee, Ratchet's old war wound tingles, making him think that trouble's ahead. Just then, the lights in the city go out, and the trio is confronted by a spiked muscle car with red headlamps. Thinking it's a human out for a joyride, the Autobots go after the car. At a critical moment in the chase, Ratchet experiences a flashback to his days in the Great War... In the middle of the repair to Arcee, Ratchet loads her up and starts to evacuate the area, only to be caught and smacked down by a bounty hunter.
