Hunter King is joining the cast of ABC’s 9-1-1: Nashville for a special flashback episode, stepping into Jessica Capshaw‘s shoes to play a younger version of her character Blythe Hart.

“This is your emergency reminder: Tune into @911nashville tonight!” Hunter wrote on Instagram.

Hunter is best known for her work in Hallmark Channel movies and from shows like Life in Pieces and The Young and the Restless.

The episode will also feature Ben Winchell as the younger version of Chris O’Donnell‘s Don Hart and Noa Bess Solomon as the younger version of LeAnn Rimes‘ Dixie Bennings.

Here’s the episode synopsis: “Flashbacks reveal how a devastating house fire reshaped Don’s life, along with how he later met Dixie and Blythe. The 113 responds to a cyclist pinned against a tree after being hit by a car.”

New episodes of 9-1-1: Nashville air on ABC on Thursday nights at 9/8c and stream next day on Hulu. The “Don Begins” episode airs TONIGHT, February 26.
