Under Salt Marsh (2026) Season 1

No secrets are safe from the storm.

Synopsis

Morfa Halen is a tight-knit Welsh town precariously nestled between towering mountains and a fast-encroaching sea that threatens its very existence. As a once-in-a-generation storm begins to gather far out at sea, former detective turned teacher Jackie Ellis discovers the body of her 8-year-old pupil, Cefin, seemingly drowned.

The discovery sends shockwaves through the community, reviving the ghost of an unsolved cold case that rocked the town three years prior – the disappearance of Jackie’s niece, Nessa, which cost her career.
