Episodes 1–3 Recap:

In the opening episodes of Under Salt Marsh, former detective-turned-teacher Jackie Ellis is pulled back into police work when she discovers the body of her young pupil Cefin, apparently drowned in the marshes of Morfa Halen, a storm-threatened coastal town, reopening the unresolved trauma of her niece Nessa’s disappearance that ended her career. The shocking discovery forces her uneasy reunion with her old partner Detective Eric Bull, as they investigate Cefin’s death amid a hostile community and rising suspicions that it may be connected to past events; by episode three, unsettling revelations emerge about local secrets, lies at the heart of the investigation, and illicit operations in town, pushing Jackie and Bull into an uneasy alliance as they follow conflicting leads and uncover deeper webs of deceit, all while a devastating storm looms that could wash away crucial evidence.

Episode 4 Recap:

In Episode 4, the tension in the Welsh coastal town of Morfa Halen reaches a new peak as Jackie Ellis grapples with the emotional fallout from recent events and the unexpected return of her estranged sister, forcing long-buried guilt and fractures in their relationship to the surface. As Detective Eric Bull delves deeper into the intertwined mysteries haunting the community — believing that the current child’s death and the disappearance of Jackie’s niece may be connected — a dramatic confession and emerging DNA evidence turn the investigation on its head, pushing both Jackie and Bull to decide whether to protect those they love or pursue a devastating truth before the storm closes in.

Episode 5 Recap:

In Episode 5, the tension in the flood-isolated Welsh town of Morfa Halen escalates as DI Eric Bull edges closer to unraveling the core mystery, uncovering that Solomon’s son Ned Bevan had found and buried Jackie’s missing niece Nessa’s body but wasn’t her killer, and that young Cefin didn’t go to the farm on the night he died, altering the investigation’s direction. As the storm cuts off all access, evidence increasingly implicates Jackie’s lover Dylan Rees, with incriminating links to the illegal waste deliveries and the type of hazmat suit drawn by both Cefin and Nessa before their deaths, prompting Jackie to confront him and putting her at risk. Bull also makes a disturbing discovery of toxic waste seeping from the sea wall construction, and by the end of the penultimate episode Cefin’s friend James has gone missing, setting up a dramatic finale.
