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 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, and Steve Zahn also set to return.
