Apple released a trailer for the third season of its sci‑fi series Silo, debuting July 3 on Apple TV+. The show follows 10,000 residents of an underground bunker, with Rebecca Ferguson returning as engineer Juliette Nichols. Based on Hugh Howey’s novels, Silo ranks among the streaming service’s most‑watched originals. The series has sparked fan theories and online discussion, boosting Apple TV+ subscriber growth.

The ten‑episode third season will drop one episode each Friday through September 4, continuing a “dystopian society” storyline. Apple describes Juliette surviving a forced “cleaning” but returning with amnesia as the silo confronts a new threat, while journalist Helen Drew (Jessica Henwick) and Congressman Daniel Keene (Ashley Zukerman) expose a fatal conspiracy. The narrative deepens the show's moral complexity. A fourth and final season is greenlit.

Apple TV+ costs $12.99 per month or $129 annually, with a free week for newcomers, and the service bundles into Apple One and Peacock packages. The series streams via the Apple TV app on iPhone, iPad, Mac, Apple Vision Pro and major streaming devices. Fans can now binge the new episodes as they arrive, closing in on the series’ ultimate mysteries.
