A family of aliens from a much better world must take refuge in middle America after the destruction of their planet. Their mission: protect the Pupa, a living super computer that will one day evolve into its true form, consume them and terraform the Earth.
Rick is a mentally-unbalanced but scientifically-gifted old man who has recently reconnected with his family. He spends most of his time involving his young grandson Morty in dangerous, outlandish adventures throughout space and alternate universes. Compounded with Morty's already unstable family life, these events cause Morty much distress at home and school.
