Under Salt Marsh (Season 1)

Under Salt Marsh (2026) is a British crime mystery you can watch online on iFILM. It unfolds in Morfa Halen, a Welsh town wedged between high mountains and a sea that keeps swallowing its coastline. Far offshore, a once-in-a-generation storm is building.

Jackie Ellis traded her detective's badge for a classroom years ago. Then she finds Cefin, her eight-year-old pupil, drowned in circumstances that don't add up. His death cracks open something the town buried three years back: the disappearance of Jackie's niece Nessa, the cold case that wrecked her career. The clock is brutal — once the storm hits, every trace washes away. Kelly Reilly carries the lead as Jackie, with Rafe Spall and Jonathan Pryce alongside her. Directors Claire Oakley and Mary Nighy keep everything damp and claustrophobic: a small community where everyone knows each other's business and that's exactly why no one talks. The tagline holds — no secrets are safe from the storm. Stream Under Salt Marsh (2026) online on iFILM.
