In a dystopian future where thousands have been living underground in a massive silo, an engineer (Rebecca Ferguson) begins to question what is actually going on in the new Apple TV+ series Silo, which debuts in May. Ferguson plays Juliette, who starts to question the purpose of the silo and if everything they were told and forced to follow is actually for their own safety or for some other purpose. The outside world is apparently toxic and deadly, which was the reason why this society fled underground into the titular silo. The show is based on a series of books by Hugh Howey. Iain Glen, Ferdinand Kingsley, Tim Robbins, Common, David Oyelowo, Shane McRae, Rick Gomez, Henry Garrett, and Angela Yeo co-star. The show was created by Graham Yost, who previously brought us Justified, Falling Skies, and The Americans. Silo begins on May 5th and you can check out the trailer below.
