The official synopsis for the series reads: “Under Salt Marsh is a gripping crime thriller set in the fictional Welsh town of Morfa Halen, a tight-knit community 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 (Reilly) discovers the body of her eight-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.

“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.

“An intimate and cinematic story, Under Salt Marsh takes audiences into the heart of a community bound by nature and fractured by an unthinkable crime.”
