Silo has received a two-season renewal at Apple TV+ with its end confirmed.
Based on a trilogy of novels by Hugh Howey, the post-apocalyptic drama follows the residents of a giant underground silo who are bound by regulations that they believe are meant to protect them.
However, as engineer Juliette Nichols (Rebecca Ferguson) begins to investigate the mysterious death of a co-worker, she encounters a mystery that goes a lot deeper than anyone could have imagined.
Silo is currently halfway through its second season on the streamer. The upcoming third and fourth seasons will take the show to the end of its story.
