Speaking previously about Under Salt Marsh, series creator Oakley pointed out the significance of Reilly’s character to the storyline, praising the brilliant actress. “At the heart of it all is Jackie, a character who embodies the wildness of the place we’re depicting,” she shared. “She’s free-spirited, compassionate, and determined, with a steely resolve that makes her truly of the land. We’re absolutely thrilled to have Kelly Reilly [bring] Jackie to life.” In addition to Yellowstone, Reilly has also appeared in ABC’s medical drama, Black Box, HBO’s anthology True Detective, and the historical fantasy Britannia, among others.

What Is ‘Yellowstone’s Kelly Reilly’s New Project About?

Under Salt Marsh is set in a fictional Welsh town called Morfa Halen, taking place as a huge storm gathers, with Jackie (Reilly) discovering the seemingly drowned body of her eight-year-old pupil Cefin. As teased by the British show’s synopsis, this sends shockwaves in the community and revives the ghost of an unsolved cold case that rocked the town three years prior, specifically the disappearance of Jackie’s niece, Nessa, which cost her career. The synopsis adds, “Cefin’s death summons Jackie’s former partner, Detective Eric Bull, back to Morfa Halen to lead the investigation into a community he failed once before. Convinced the cases are linked, Jackie and Bull must reconcile and race to uncover long-buried secrets inside Morfa, before the storm breaks and all the evidence is gone for good.”

A premiere date for Under Salt Marsh should be expected soon. Stay tuned to Collider for more information.
