The end of the world had a beginning.

Season three of “Silo” continues the saga of a dystopian society of 10,000 people living underground under mysterious circumstances, while revealing an origin story set centuries earlier. In the present,

Juliette Nichols (Ferguson) survives her forced “cleaning” but returns with memory loss as the silo recovers from rebellion and faces a dangerous new threat.

Meanwhile, in the “Before Times,” 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 series is based on Hugh Howey’s New York Times bestselling trilogy, “Silo.”

The ensemble cast returning alongside Ferguson includes Common, Harriet Walter, Chinaza Uche, Avi Nash, Alexandria Riley, Shane McRae, Remmie Milner, Rick Gomez, Billy Postlethwaite and Clare Perkins.

Joining the cast for season three are Zukerman and Henwick, who appeared in the season two finale, along with Laura Innes, Jessica Brown Findlay, Morven Christie, Reed Birney and Matt Craven, with Colin Hanks set to recur. Steve Zahn will also return.

Silo Season 3 returns on Apple TV from July 3.
