The current season consists of 10 episodes, with the finale scheduled for release on September 4, 2026.

Background

Based on a dystopian premise where humanity lives in a massive underground structure, the series first premiered in 2023.

The narrative has evolved to utilize a dual-timeline structure. One plotline follows the immediate consequences of a rebellion within Silo 18, while a secondary arc serves as an origin story set centuries earlier, featuring characters such as Congressman Daniel Keene and journalist Helen Drew as they investigate the conspiracy behind the silos.
