In this Emmy Award winning comedy, average guy Tandy (Will Forte) inadvertently becomes the only man left on Earth after a deadly virus sweeps the planet in 2020. Slowly but surely a handful of other survivors finds Tandy, who has returned to his hometown of Tucson. In Season Four, the survivors continue their journey through a post-virus world, setting sail toward Mexico to avoid nuclear fallout. The boat, which no one really knows how to street, get a bit more crowded as wealthy socialite Pamela (guest star Kristen Wiig) and her dog get on board.
