"Fire Country" is getting not one but two major new additions for its upcoming fifth season.

Following Eric Guggenheim’s arrival as executive producer and showrunner, the CBS firefighter drama has cast Olivia Thirlby (Oppenheimer, Y: The Last Man) as a new series regular for Season 5.



She will play a new firefighter, CJ.

Cecilia Jade “CJ” Ryan is a quick-witted, fiercely independent, blue-collar, decorated urban firefighter who bolted her station house and city for mysterious reasons. After six months on the road, trying to outrun whatever happened, and herself, fate strands her in Edgewater where she crosses paths with Bode.

Despite having no experience fighting woodland fires, Bode believes CJ has something to offer Station 42. And despite the serious culture shock, this fish out of water comes to believe rural Edgewater has something to offer her.
