Sky has released a first look at ‘Under Salt Marsh’, a brand-new Sky Original crime drama starring Kelly Reilly (Yellowstone, Pride & Prejudice) and Rafe Spall (Trying, Life of Pi), set to arrive on Sky and NOW in 2026.
Created, written and directed by Claire Oakley (Make Up), the six-part series takes place in the fictional Welsh town of Morfa Halen. The story opens as a once-in-a-generation storm rolls in from the sea. Former detective turned teacher Jackie Ellis (Reilly) makes a shocking discovery that reopens the wounds of a three-year-old cold case which cost her both her career and her family’s trust.
Forced to reunite with her estranged police partner Eric Bull (Spall), Jackie is drawn back into an investigation that threatens to shake Morfa Halen to its core. With the community haunted by secrets and fractured by grief, the pair must find the truth before the incoming storm washes away the evidence forever.
The supporting cast is just as strong, featuring Naomi Yang (Chimerica), Jonathan Pryce (The Crown), Dinita Gohil (Treason), Brian Gleeson (Bad Sisters), Kimberley Nixon (Queenie), and Harry Lawtey (Industry). Sky teases that ‘Under Salt Marsh’ will combine brooding, atmospheric crime storytelling with a deeply human portrait of resilience and community.
The series is produced by Little Door Productions in association with Sky Studios, with support from the Welsh Government via Creative Wales. Writing comes from Oakley, Jonathan Harbottle (episodes 3 & 5) and Nikita Lalwani (episode 4). Claire Oakley leads the direction, with Mary Nighy helming episodes 3 and 4. Producers are Scott Bassett and Emma Duffy, while Executive Producers include Elwen Rowlands for Little Door Productions, Megan Spanjian for Sky Studios, Claire Oakley, and Kelly Reilly herself.
