During one of their adventures in outer space, Rick and Morty's ship suffers a flat tire. While they carry out repairs, Morty suffers a potentially lethal snake bite that leads to a complicated, time-travelling encounter with a snake civilization.
Rick promises Morty he can get a new companion: a flying, fire-breathing dragon. Jerry meets a mysterious talking cat.
At the end of a treasure-hunting expedition, Rick discovers that the loot he and Morty sought had already been nabbed by the heist artist Miles Knightly. Furious at being upstaged, Rick recruits a crew required to gain entrance into Heist-Con as "professionals" so he can confront Miles.
Rick discovers that someone has been using his private "rest stop" and sets out to find them. Meanwhile, despite being warned not to, Jerry develops an app with Rick's alien intern, and chaos ensues.
Rick brings Morty to a planet containing crystals that show whoever is touching them all the ways they may die depending on their choices.
