Tony-award winning actress Joan Allen has joined ABC’s untitled Jenna Bans pilot.

The network announced on Thursday that Allen will portray the character Claire in the pilot, written by Bans (Private Practice producerand co-executive producer on Grey’s Anatomy and Scandal). It follows the return of a politician’s son who was presumed dead after disappearing over a decade ago, an event that sends shockwaves through his close family.

But while the mysterious young man is welcomed back by his community, the neighbor who was imprisoned for his murder is released and the cop responsible for the arrest is forced to reexamine what truly happened all those years ago.

Other than Allen, the pilot’s cast currently includes Zach Gilford as Danny, Liam James as Adam, Margot Bingham as Sergeant Nina Meyer, and Floriana Lima as Bridey.
