Fallout is a 2024 post-apocalyptic science fiction series created by Geneva Robertson-Dworet and Graham Wagner for Amazon Prime Video, produced in partnership with Bethesda Game Studios, the developer behind the iconic Fallout video game franchise. Set in the same retro-futurist universe as the games, the series unfolds across a radioactive American wasteland centuries after nuclear war, where competing factions, irradiated survivors, and the remnants of corporate power struggle for dominance over what remains.

The series follows Lucy MacLean (Ella Purnell), a young woman raised inside Vault 33 — one of the underground shelters constructed by the Vault-Tec Corporation to protect a curated selection of Americans from the bomb, enforcing an optimistic, rigidly ordered society sustained by propaganda and social control. When Lucy ventures to the surface for the first time, she crosses paths with Maximus (Aaron Moten), an idealistic soldier of the militaristic Brotherhood of Steel, and The Ghoul (Walton Goggins), a pre-war bounty hunter whose centuries of irradiated survival have transformed him into something between a mythic cowboy and a philosophical monster. All three are propelled toward a common mystery that cuts to the heart of the wasteland's most powerful secrets.

Fallout became one of the most-watched series in Amazon Prime Video's history at the time of its launch, praised for honoring the tone, lore, and retrofuturist aesthetic of the game franchise while constructing an entirely original story accessible to non-players. The show was renewed for a second season before its first had finished airing, and critics celebrated its extraordinary production design, the chemistry of its central trio, and especially Walton Goggins' performance as The Ghoul — a character study in centuries of accumulated bitterness and unexpected humanity.
