BETTER Than Mare of Easttown?! Kelly Reilly Explodes Onto Screens in Under Salt Marsh — A Haunting 6-Part Crime Thriller That Will Tear a Town Apart

September 25, 2025 — Television audiences are bracing themselves for one of the most gripping British crime dramas of the year. Under Salt Marsh, a six-part thriller starring Yellowstone’s Kelly Reilly and Rafe Spall, is already being hailed as “bigger than Mare of Easttown” and drawing comparisons to the acclaimed Broadchurch. With its atmospheric storytelling, dark secrets, and a deeply human core, the series promises to be the unmissable drama of 2026.

At the center of the series is Kelly Reilly as Jackie Ellis, a former detective whose career, family, and life were shattered by a single cold case. When a shocking new discovery reopens that long-forgotten investigation, Jackie is forced to confront a town haunted by secrets, betrayals, and grief. Reuniting with her estranged partner Eric Bull, played by Rafe Spall, she must navigate a dangerous maze of lies where every revelation threatens to upend the fragile stability of Morfa Halen — the fictional Welsh town at the heart of the drama.

A Cold Case That Shattered a Career and a Family

The premise of Under Salt Marsh is as emotionally charged as it is thrilling. Three years ago, a case went horribly wrong, costing Jackie Ellis not only her badge but also the trust of her family. Now, when evidence resurfaces, the detective-turned-teacher is dragged back into a storm of deceit, corruption, and grief that threatens to engulf the entire community.

From the moment Kelly Reilly steps onto the screen, viewers are drawn into Jackie’s turmoil. She embodies a fallen hero, haunted by the past and forced to reckon with both personal and professional demons. Her performance promises to be a masterclass in emotional complexity, blending steely determination with vulnerability and the lingering scars of betrayal.

Rafe Spall, portraying Eric Bull, provides the perfect foil: a man whose own secrets and regrets mirror Jackie’s in unexpected ways. Their uneasy reunion sets the stage for a series filled with tension, suspense, and the type of character-driven storytelling that has made shows like Broadchurch and Mare of Easttown cultural touchstones.

Atmospheric Crime Storytelling at Its Best

Under Salt Marsh isn’t just a crime drama; it’s an atmospheric exploration of human resilience and the long shadows cast by grief and secrecy. Set against the windswept coastline and brooding streets of Morfa Halen, the series uses its setting to amplify tension, mirroring the storm that threatens to wash away both evidence and stability.

Each episode peels back layers of deception, revealing that beneath the town’s picturesque facade lie fractures that could destroy lives. From the subtle glances of neighbors hiding secrets to the whispers of local officials covering up their missteps, every interaction adds a new thread to a web of suspense so intricate that viewers will find themselves guessing until the final scene.

The Cast That Brings Morfa Halen to Life

In addition to Kelly Reilly and Rafe Spall, Under Salt Marsh boasts an extraordinary supporting cast. Naomi Yang (Chimerica), Jonathan Pryce (The Crown), Dinita Gohil (Treason), Brian Gleeson (Bad Sisters), Kimberley Nixon (Queenie), and Harry Lawtey (Industry) each bring depth and nuance to a series already rich in character drama. Their performances promise to elevate the suspense, grounding the series’ high-stakes thriller elements in emotional reality.

Claire Oakley, known for her work on Make Up, serves as creator, writer, and director, ensuring a cohesive vision that balances tension, character development, and thematic resonance. Oakley’s previous projects have demonstrated her ability to tackle complex emotional material with sensitivity and sophistication — a skill that promises to shine in Under Salt Marsh.

A Story of Secrets, Betrayal, and Redemption

What sets Under Salt Marsh apart from other crime dramas is its commitment to exploring the human cost of deception. Jackie Ellis’s journey is as much about unraveling the town’s secrets as it is about confronting her own failings and regrets. As she and Eric navigate a community fractured by loss, audiences witness the interplay of guilt, loyalty, and the desperate desire for justice.

The storm that looms over Morfa Halen is both literal and metaphorical, symbolizing the chaos unleashed when truth finally surfaces. With each episode, viewers will see lives intertwined, betrayals laid bare, and the thin line between justice and revenge tested to its limits.

Viewer Reactions and Anticipation

Though the series is set to air in 2026, anticipation is already building. Fans of Kelly Reilly, known for her work in Yellowstone and critically acclaimed British dramas, are marking calendars, eager to witness her transformative performance. Social media buzz highlights the suspense, intrigue, and the promise of a narrative that is as emotionally gripping as it is thrilling.

Early teasers have been met with enthusiastic speculation, with audiences drawing parallels to Broadchurch while noting that Under Salt Marsh appears to promise an even darker, more psychologically complex narrative. The show’s combination of atmospheric cinematography, intricate plotting, and powerhouse performances has positioned it as a must-watch for crime drama aficionados.

Sky and NOW: A Perfect Home for the Series

While Sky has yet to announce an exact release date, Under Salt Marsh is confirmed to launch on both Sky and NOW in 2026. The dual-platform approach ensures accessibility for a wide audience, allowing viewers to stream at their convenience while still engaging with the communal excitement of a weekly television event.

In the meantime, Sky’s autumn lineup includes other highly anticipated dramas, such as The Iris Affair starring Tom Hollander and Niamh Algar, and All Her Fault, led by Sarah Snook, demonstrating the network’s commitment to high-quality storytelling that combines suspense, character depth, and cinematic ambition.

Why Under Salt Marsh Could Redefine the Crime Drama Landscape

Under Salt Marsh has all the elements of a game-changer. Its combination of:

• A star-studded cast led by Kelly Reilly and Rafe Spall

• Atmospheric storytelling that captures both place and mood

• A narrative that intertwines suspense with deeply human themes of loss, betrayal, and redemption

• Direction by Claire Oakley, whose sensitive yet bold approach elevates the material

…makes it a series that could not only captivate viewers but also influence the trajectory of British crime dramas in the coming years.

Unlike formulaic procedurals, the show emphasizes character, emotional stakes, and moral complexity, asking audiences to wrestle with questions of justice, loyalty, and the consequences of buried secrets. This human-centered approach ensures that Under Salt Marsh is more than entertainment — it is a reflection on the ways that personal and communal histories collide when truth finally emerges.

The Emotional Core of the Series

At its heart, Under Salt Marsh is a study in resilience. Jackie Ellis’s character embodies the tension between duty and personal pain, between public responsibility and private grief. Her journey through a community haunted by a storm — both meteorological and emotional — resonates with anyone who has confronted betrayal, loss, or the need to make peace with the past.

Rafe Spall’s Eric Bull provides a counterbalance, portraying a character whose own flaws, regrets, and loyalties challenge and enrich Jackie’s story. Their dynamic is electric, charged with unresolved tension, mutual respect, and the weight of shared history. Each confrontation and collaboration between them is a masterclass in narrative tension and character development.

A Cinematic Approach to Television

The series’ production design, cinematography, and soundscape elevate Under Salt Marsh beyond typical crime dramas. Wind-swept coastlines, mist-laden streets, and the brooding architecture of Morfa Halen create a visual atmosphere that mirrors the psychological intensity of the story. Music and ambient sound heighten suspense and underscore emotional beats, drawing viewers fully into the world Oakley has meticulously crafted.

Conclusion: The Must-Watch Drama of 2026

With a combination of star power, a gripping narrative, and evocative production, Under Salt Marsh is positioned to be one of 2026’s most compelling television events. Kelly Reilly delivers a performance that promises to be career-defining, while Rafe Spall provides equal measure of nuance and intensity.

For audiences craving suspense, emotional depth, and a story that blends the psychological complexity of Mare of Easttown with the haunting atmosphere of Broadchurch, Under Salt Marsh is the ultimate must-watch. From the opening storm to the final revelation, every episode promises tension, heartbreak, and moments that will linger long after the credits roll.
