Filmyhype.com Ratings: 4/5 (four stars)
There is a subtle, constant uneasiness that runs through Under Salt Marsh from the first minutes and no longer abandons the viewer. The series, available on NOW and Sky Atlantic, tells a story of a criminal investigation, avoiding narrative shortcuts and relying instead on atmosphere, silences, and characters marked by wounds that time has not healed. Set in the Welsh coastal town of Morfa Halen, threatened by rising seas and an impending storm, the story weaves together the mystery of a child’s death with an unresolved past that continues to weigh on the present. At the center of the story are Jackie Ellis, played by Kelly Reilly, and Detective Eric Bull (Rafe Spall); surrounding them is a closed, distrustful community that seems to reflect deep emotional distress in its geographic isolation.
Old, murky waters stagnate in the swamp. The natural watercourse stops, gets bogged down, finds no more soil to flow on, and then languishes, stuck, in a slimy mass of waste. Under everything can be buried there: mud, debris, quicksand, unknown fauna, and even secrets. Which remain buried, submerged, at least until someone decides to undertake a cleanup operation. Under Salt Marsh It’s already a manifesto of intent in the title: there’s something beneath the surface, beneath the salt marsh, that needs to be dug up, that needs to come back to the surface. It is one of the more interesting news stories of this kind to keep an eye on in February. It is a six-part series, created, written, and directed by Claire Oakley. In the cast, there are Kelly Reilly and Rafe Spall in the role of investigators and Naomi Yang, Jonathan Pryce, Dinita Gohil, Brian Gleeson, Kimberley Nixon, and Harry Lawtey, as well as Mark Stanley, Dino Fetscher, Lizzie Annis, Rhodri Meilir, and Julian Lewis Jones.
Under Salt Marsh Series Review: Story Plot
The body of nine-year-old Cefin was found in a drainage canal. It shakes Morfa Halen more than the population is willing to admit. The body was discovered by Jackie Ellis (Kelly Reilly), a primary school teacher, already affected by the disappearance of her niece Nessa three years earlier. That loss, never clarified, comes back to force when Detective Eric Bull (Rafe Spall), the same investigator who had followed the little girl’s case, arrives on the scene. An unresolved tension immediately emerges between the two, made up of unspoken accusations and a shared past that continues to influence every gesture. While the investigation reveals that Cefin’s death may not be a simple accident, seemingly marginal details begin to suggest disturbing links to Nessa’s disappearance. In a context where everyone knows each other and nothing can remain hidden for too long, each new lead risks destabilizing already fragile balances, exposing secrets that the community would have preferred buried forever.
The series, the synopsis explains, tells of a mysterious murder in a small town that brings dark secrets back from the past, while an impending storm from the sea, the kind that happens once in a generation, threatens to erase evidence of it forever. The series opens with Jackie Ellis, a former detective turned teacher, making a shocking discovery: she finds Cefin, one of her nine-year-old students, in a pool. He’s dead. A drama that reopens the wounds of an unsolved case three years earlier, which cost her both her career and the trust of her family: the disappearance of her niece, Nessa. Forced to reunite with her former police partner, Eric Bull, from whom she had now distanced herself, Jackie is drawn back into an investigation destined to shake Morfa Halen to its foundations. Together, they will face a community haunted by secrets and broken by grief, before the coming storm erases the evidence forever.
Under Salt Marsh Series Review and Analysis
The series mixes investigations and secrets and takes us to a community on the edge. Isolated, squeezed between the mountains and the sea, constantly threatened by the water, but determined to stay there. It is an investigation, but also a journey into the human. In pain, in guilt, in resilience, in retaliation. But also in the secrets, lies, and dark corners of lives. It’s a series that is mystery and therapy at the same time. The writing by Claire Oakley, Jonathan Harbottle, and Nikita Lalwani is shrewd. The series starts from a plot that is certainly not new, but it is the execution that counts: the well-measured details, the lilting clues, the layered symbolism. From the storm to the choices of the protagonists, from the silences to the screams, everything is measured.
The direction of Claire Oakley and Mary Nighy, then, is patient and precise. You travel in fast, but not forced, stages. The mystery thickens, and as time runs, anxiety rises. The preciousness is here: the “emptiness” of the action is filled by the setting, which becomes an integral part of the narrative. The atmosphere is thin and at the same time heavy. Photography, finally, is fundamental: landscapes and colors that, in turn, conceal secrets. Added to all this is the acting performance of Kelly Reilly, Rafe Spall, and Jonathan Pryce. Under Salt Marsh strong part. Two episodes – those we had available for review – immediately set the bar at a nice high point.
One of the most successful elements of the series is louse of space as an integral part of the narrative. The swamps, the makeshift embankments, and the slowly but surely advancing sea are not simple sets, but active presences that influence the characters’ behavior. Morfa Halen is a suspended place, constantly teetering between resistance and surrender, and this environmental precariousness becomes a clear metaphor for the emotional tensions that run through its inhabitants. The direction insists on low skies, closed horizons, solitary walks in the mud, building a sense of oppression that accompanies the development of the investigation and amplifies the feeling of threat, both natural and human.
While moving within the confines of the investigative thriller, Under Salt Marsh proves to be above all a reflection on mourning and its consequences. The loss of a son, a granddaughter, a point of reference leaves different marks on each character, and the series takes the time to show them without resorting to easy emotional solutions. Cefin’s parents are never reduced to narrative functions, but are told in their disorderly suffering of anger, bewilderment, and awkward silences. Jackie, too, is a figure who escapes any label: her often ambiguous behavior stems from an unprocessed pain that pushes her to make decisions that are difficult to judge from the outside. In this sense, mystery becomes the means through which to explore a collective wound that has never stopped bleeding.
To immediately let the viewer into the mood of Under Salt Marsh – Submerged Secrets It’s Claire Oakley’s writing, which gets straight to the point while keeping the pace high. But above all, his direction, while the photography colors a murky and complex story with nuances. The shades are not only dark but also green and blue of the sea, which manage to express all the facets of the feelings that the characters go through: pain, loss, resilience, resentment, and guilt. The five stages of grief processing in thriller sauce; family ties too often castrating rather than liberating.
There’s a whole world to discover in Marfa Halen, a microcosm perched between sea and mountain, trying to keep its identity solid. A place that is about to face a storm, not only physical but also emotional. A town where no one locks the door because there is Community confidence mutual; yet the same is about to be questioned, perhaps forever, precisely because of those secrets that, by wanting to remain buried, have turned to mold. And you start to smell it. The series deliberately chooses to go slowly, piling up clues and suspicions without offering immediate answers. There are no obvious culprits nor revelations constructed to surprise at any cost. On the contrary, the writing prefers to follow the underground connections that bind the characters, showing how, in an isolated community, every event ends up having numerous repercussions.
Under Salt Marsh asks the viewer for patience and attention, but in return offers a solid psychological thriller, capable of going beyond the simple enigma and conveying the believable portrait of a community cornered by its own faults and the unstoppable force of nature. Under Salt Marsh is a perfect series for an investigative mystery. Dark photography, cold scenography, a catastrophe on the horizon, and an inhospitable external environment form the framework for the events narrated. The pilot immediately reveals the common thread that connects with our present: environmental disasters and the metamorphosis of some areas of the planet. Morfa Halen is surrounded by water, a strip of land that risks being sucked in by the tides and rising sea levels. Heavy rain is about to fall on the area, one of those adverse weather events that immediately trigger a red alert. The town has been notified, but residents are not even thinking about leaving their homes.
The people of Morfa Halen were born and raised in that place and have no intention of abandoning it, which is why they are building an embankment to keep rising waters at bay. What, though he wants to come to the surface, overflowing with virulence, is not just seawater. There are secrets and old unsolved cases ready to resurface and overwhelm everything in Morfa Halen. The truth is not a postscript to be added by pen under a file. It’s an exhausting process that, along the way, leaves individuals bent and destroyed. The case of Cefin’s death is not the only one to have disrupted the town in its recent history. Nessa, a 9-year-old girl and Jackie’s niece, is the face of another unsolved case. The little girl had disappeared three years earlier in circumstances that have never been clarified, and the police investigation came to nothing.
From what we understand from the first two episodes of Under Salt Marsh, the lives of Jackie and Detective Bull were devastated by that event. Jackie left the police force because she was betrayed by her partner, Bull, in fact, who had accused her sister, Lydia, of murder. An unsolved case, in short, which still leaves deep wounds in the characters. Cefin and Nessa: two children, two victims, two tangled cases that Jackie tries to solve. We understand that there is immediately something very personal in the protagonist’s way of acting; little by little, we will see new pieces of the woman’s past emerge. Under Salt Marsh connects the two cases, forcefully brings the past back to light, and places the investigations in a particular context, because the town of Morfa Halen is about to be swept away by a storm, along with all the clues and the truth about the case.
One of the first suspects is Osian, an old man who goes around proclaiming the coming of the apocalypse, scaring everyone, including children. However, his guilt would be too trivial, and in fact, Jackie immediately excludes him. The other individual to end up in the crosshairs of the investigation is Kieran Benbow, a man who lives on the sidelines and raises bees, who, for Jackie, was involved in the case of his niece’s disappearance. Under Salt Marsh 1×02 shows, however, that the links between Cefin and Kieran were of another kind. Family secrets intertwine with the leads of the case, in a crescendo of anguish well managed by the first two episodes. Everyone becomes a potential suspect; everyone acts like they have something to hide.
Someone moved Cefin’s body, abandoning it in a pool of fresh water. Someone who is part of the community, who walks among Cefin’s family, who perhaps exchanges a few chats with them. And it’s Cefin’s own family who have more than one secret to hide, just like everyone else. Under Salt Marsh, therefore has so much material to dig up from the salt marsh. There are only 6 episodes of the series, so the action will have no moments of stagnation, and the investigation will proceed at a rapid pace. Also, because the storm is coming, discovering the truth will be a race against time. In the final scene of Under Salt Marsh, Jackie and Bull discover a quarry full of waste far from the town center. Cefin likely spent the last hours of his life there, but why? What was a 9-year-old doing in a place like this? This is the first question that the two protagonists of Under Salt Marsh, who have just lifted the lid of a cauldron full of mysteries and dark secrets, which we will discover in the coming weeks.
Under Salt Marsh Series Review: The Last Words
Under Salt Marsh patiently builds his tale, letting silences, landscapes, and unresolved relationships drive the tension. The investigative case never really dominates the scene, but it functions as a lens through which to observe a fragile and divided community. The series avoids easy solutions and rejects the spectacularization of pain, preferring a more humane and restrained approach.
The central performances are solid and believable, capable of returning complex characters without ever making them completely likable or repulsive. The result is a dark but lucid tale, which demands attention and restores depth. Under Salt Marsh is a mystery and thriller miniseries that expertly combines investigations and family ties, with two immediately defined protagonists and a story that begins in medias res in a charming and symbolic town. Two excellent performers in Kelly Reilly and Rafe Spall, a good supporting cast led by Jonathan Pryce, and rarefied direction and cinematography make her the (almost) heir to Broadchurch.
