Silo (2023)

Silo is the story of the last ten thousand people on earth, their mile-deep home protecting them from the toxic and deadly world outside.

Rebecca Ferguson stars as Juliette, an engineer, who seeks answers about a loved one's murder and tumbles onto a mystery that goes far deeper than she could have ever imagined, leading her to discover that if the lies don't kill you, the truth will.
