The episode largely takes place in Zeep's microverse, with Rick, Morty and Zeep attempting to escape it.
Plot
On a trip to an alternate dimension, Rick, Morty, and Summer discover that Rick's car battery is malfunctioning. Rick takes Morty inside the car battery to repair it and leaves Summer waiting in the car, instructing it to "Keep Summer safe." Morty discovers that the car battery is actually a 'microverse battery', containing an entire universe to supply power to the car. Rick gave " box" technology to an intelligent species to generate electricity, but unbeknownst to them he takes a majority of the generated power. This leads Morty to question Rick's ethics.
Rick and Morty discover that a scientist and microverse citizen named Zeep Xanflorp (Stephen Colbert) has made his own 'miniverse', which renders boxes obsolete. Rick, Morty and Zeep enter the miniverse, and discover that Kyle, a scientist living in Zeep's battery, is also working on his own 'teenyverse', which Morty and the three scientists enter. Once both Zeep and Kyle discover that they are slaves born to make electricity, Zeep attacks Rick in a rage. During the struggle, Kyle commits suicide using his spaceship, leaving Rick, Morty, and Zeep stranded in the teenyverse.
