After Summer blows his cover, Rick flees a shady deal with space mobsters and ends up stranded with the kids on a planet mysteriously devoid of any technology they could use to repair the ship. When they're intercepted by savage, furry loincloth-wearing versions of themselves, they discover technology has been forcibly removed from this society, along with their hopes for an easy escape. Will it be enough for Rick to find a way off planet, or does he also have to prove who's the Rickest Rick of them all?
