A clash with Autobots forces Quintessons to flee. A Quadrant Lock is the Quintessons' only possibly refuge, but things go very wrong. The Autobots and the Quintessons find themselves unable to exit the Quadrant Lock the way they entered, and they aren't alone. It turns out that the entire planet Zimojin has spent thousands of years there because of the Quintessons. Naturally, the Zimojins still hold quite a grudge. The key to escape for all ultimately lies in Perceptor, but Katsudan inadvertently gives him trouble first.
