The third season premieres July 3 with a dual narrative spanning centuries
Before Severance and Pluribus became Apple TV’s two biggest sci-fi phenomena, Silo was arguably the streamer’s first mainstream breakout in the genre. Now two seasons in, the highly anticipated third chapter is almost here, and a new trailer has offered the clearest look yet at where the story is heading.
Season three premieres July 3 with a single episode, followed by weekly releases every Friday through September 4.
The trailer reveals that the new season will unfold across two distinct timelines. In the present, Juliette Nichols (Rebecca Ferguson) survives her forced cleaning but emerges with no memory of who she is or what she has been through. Three months have passed since her ordeal in what Robert Sims (Common) describes as “a box of fire,” and in her absence someone has been filling in the blanks for her. Camille Sims (Alexandria Riley) appears to be feeding Juliette a carefully constructed false narrative, guided by a mysterious presence known only as The Algorithm. Fragments of memory are beginning to return, but Camille is convinced that if Juliette remembers the truth, everyone will be in danger. Meanwhile the silo itself is running out of time, with a countdown ticking in the background and the ominous suggestion that the public must not find out how little of it remains.
The second thread travels in the opposite direction entirely, into what the show calls the Before Times. Journalist Helen Drew (Jessica Henwick) and Congressman Daniel Keene (Ashley Zukerman), both of whom appeared briefly in the season two finale, take on expanded roles here as they uncover a conspiracy that pulls them into a chain of events with catastrophic and irreversible consequences. This storyline will serve as the origin story of the silos themselves, tracing the world-threatening event that forced humanity underground in the first place.
The returning ensemble includes Common, Harriet Walter, Chinaza Uche, Avi Nash, Alexandria Riley, Shane McRae, Remmie Milner, Rick Gomez, Billy Postlethwaite and Clare Perkins. Joining them are Laura Innes, Jessica Brown Findlay, Morven Christie, Reed Birney and Matt Craven. Colin Hanks recurs throughout the season, and Steve Zahn returns as the fan favourite Jimmy Conroy, whose fate was left unresolved at the end of season two.
The series is created and showrun by Emmy Award winner Graham Yost, based on Hugh Howey’s New York Times bestselling trilogy. Ferguson also serves as an executive producer alongside Yost, Michael Dinner, Nina Jack, Morten Tyldum, Howey and others.
Silo has already been renewed for a fourth and final season, which will complete the story of Howey’s novels and bring the series to a close. Seasons one and two are now streaming on Apple TV.
