A team of four aliens escape their exploding homeworld, only to crash-land in a move-in-ready house in suburban America. They have different opinions on whether Earth is terrible or wonderful. Korvo (Justin Roiland) and Yumilac (Sean Giambrone) only see pollution, crass consumerism, and human foibles, while Terry (Thomas Middleditch) and Jesse (Mary Mack) love humans and all their TV, junk food, and fun stuff. Their mission is to protect Pupa, a living supercomputer that will one day evolve into its true form, devour them, and terraform the Earth.
