Summer exhumes the remains of alternate Rick in their backyard, intending to use his portal gun and rescue him. Morty, however, attempts to reveal Rick's shortcomings to Summer by taking her to his original dimension — now a universe where Earth has been transformed into a wasteland by a virus turning all humans to hideous monsters as a consequence of Rick's carelessness (referred to as "the Cronenberg World"). All the while, Galactic Federation scientists attempt to discover the secret to Rick's portal gun by sending alien Cornvelious Daniel into his mind to interrogate him, using mental images from his past.
