“Season three of Silo reveals an origin story set centuries earlier while continuing the saga of a dystopian society of 10,000 people living underground under mysterious circumstances. In the present, Juliette Nichols (Ferguson) survives her forced ‘cleaning’ but returns with memory loss as the silo recovers from rebellion and faces a dangerous new threat,” reads Apple TV’s synopsis. “Meanwhile, in the ‘Before Times,’ journalist Helen Drew (Henwick) and Congressman Daniel Keene (Zukerman) uncover a conspiracy that pulls them into a chain of events with catastrophic, irreversible consequences.”
The series is based on Hugh Howey’s bestselling sci-fi trilogy. Emmy winner Graham Yost created the series, serves as showrunner, and executive produces. Additional executive producers include Michael Dinner, Nina Jack, Joanna Thapa, Rebecca Ferguson, Morten Tyldum, Howey, Amber Templemore, Fred Golan, Rémi Aubuchon, and AMC Studios.
