The first trailer for Silo season 3 has arrived, and it's just as ominous as we expected.

In the brief clip, which can be viewed above, we see a montage of chaotic clips that appear to be moving in reverse. "Before we can know why we're here... " Juliette says in a voiceover narration. "Before we can understand, before we can know why everything is the way it is, before we can begin..." The voiceover trails off until the title screen appears and reads, "The truth will set you free," alongside the penultimate season's July 3 release date.

According to Deadline, Silo season 3 follows a dual timeline: "Juliette (Rebecca Ferguson) survives her forced 'cleaning' but returns with memory loss as the silo recovers from rebellion and faces a dangerous new threat." Meanwhile, centuries earlier, "journalist Helen Drew (Jessica Henwick) and Congressman Daniel Keene (Ashley Zukerman) uncover a conspiracy that pulls them into a chain of events with catastrophic, irreversible consequences."

The hit sci-fi series is based on the trilogy of the same name by author Graham Yost, with each season serving as an adaptation of each book (Wool, Shift, and Dust). The final book, Dust, will be told over seasons 3 and 4. Season 4, the final season, wrapped filming earlier this year, but does not yet have a release date.

Silo season 3 is set to hit Apple TV Plus on July 3, with episodes airing each week until September 4. For more, check out our list of the best new TV shows coming your way in 2026 and beyond.
