Kelly Reilly, renowned for her role as Beth Dutton in Yellowstone, is set to captivate audiences once again in the upcoming six-part crime thriller Under Salt Marsh. This British series, slated for release in 2026, promises to deliver a compelling narrative filled with suspense, emotional depth, and intricate character dynamics.

Premise and Setting

Under Salt Marsh is set in the fictional Welsh town of Morfa Halen, a close-knit community nestled between mountains and the encroaching sea. The story begins as a once-in-a-generation storm begins to form far out at sea, setting the stage for a series of events that will unravel the town’s darkest secrets. Jackie Ellis (played by Kelly Reilly), a former detective turned teacher, makes a shocking discovery—the body of her 8-year-old pupil, Cefin, who appears to have drowned. This discovery sends shockwaves through the community and reopens the wounds of an unsolved case from three years prior—the disappearance of Jackie’s niece, Nessa, which cost her both her career and her family’s trust.

Character Dynamics

The tragic death of Cefin brings back Jackie’s former partner, Detective Eric Bull (Rafe Spall), to lead the investigation in a community he previously failed. Convinced that the two cases are linked, Jackie and Eric must reconcile their strained relationship and work together to uncover long-buried secrets within Morfa Halen before the impending storm washes away all the evidence.

Themes and Tone

Under Salt Marsh delves into themes of guilt, redemption, and the complexities of human relationships. The series explores how past traumas and unresolved issues can resurface, forcing individuals to confront their demons. The looming storm serves as a metaphor for the emotional turmoil and impending revelations that threaten to engulf the characters.

Production and Filming

The series is created and directed by Claire Oakley, known for her work on Make Up. Filming began in October 2024, with production taking place entirely in Wales, utilizing locations in Barmouth, Fairbourne, Anglesey, and South Wales. The choice of setting adds authenticity and atmosphere to the narrative, with the rugged Welsh landscape playing a pivotal role in the storytelling.

Cast and Performances

Kelly Reilly’s portrayal of Jackie Ellis is expected to showcase her range as an actress, moving beyond her iconic role in Yellowstone to embody a complex character grappling with personal and professional challenges. Rafe Spall’s return as Detective Eric Bull adds depth to the dynamic between the two leads, promising compelling interactions and emotional resonance. The supporting cast includes Jonathan Pryce, Naomi Yang, and Harry Lawtey, each bringing their unique talents to the series.
