For the characters of the Apple TV+ series Silo, life is defined by immense uncertainty. Adapted from the book series of the same name by Hugh Howey, it places us in a dystopian future deep underground where thousands of residents are told that the world above is uninhabitable and going there means death. Skepticism about this reality is baked in from the start — any discussion of the past is not just frowned upon, but heavily criminalized. If anyone were to even say they wanted to go see the outside world for themselves, they are subsequently forced to do so and abandoned to perish alone. All of this is first seen through the eyes of a couple trying to have a child. Allison (Rashida Jones) works in IT while Holston (David Oyelowo) is the sheriff of the entire silo. When they discover information that they aren’t supposed to, they come to doubt all of what they have been told. However, rather than follow them while they begin to piece it together and challenge the rules that govern their lives, the series pulls away to take us on the journey of another. It falls to the engineer Juliette, played by a spectacularly stoic Rebecca Ferguson, to find the truth when no one else will.
