🔥💥 ITV’s Explosive New 6-Part Affair Drama Promises to Be the Most Addictive Watch of the Year
“ITV’s Adultery Is Coming — The Raw, Twist-Filled Affair Drama That Could Be Britain’s Answer to Harlan Coben”
Introduction: The Next Big British Drama?
British television is entering another golden age of domestic thrillers, and at the center of this storm is Adultery, ITV’s upcoming six-part drama written by Danny Brocklehurst. For fans of emotional entanglements, family secrets, and stories where desire collides violently with morality, this is shaping up to be one of 2025’s most addictive small-screen offerings.
The project has been described as “naturally authentic and bristling with passion”, a tagline that has already set critics buzzing about its potential to become a cultural flashpoint. With themes of love, betrayal, grief, and the chaos unleashed by unchecked temptation, Adultery might just be the boldest story ITV has put forward in years.
But what exactly is Adultery about, and why is it already drawing comparisons to the work of thriller maestro Harlan Coben? Let’s dive deep into everything we know so far about this explosive series.
Danny Brocklehurst: The Master of Messy Human Drama
To understand why Adultery is such a big deal, you first need to understand its creator. Danny Brocklehurst has carved out a reputation as one of Britain’s sharpest screenwriters, with credits ranging from the gritty comedy Brassic to the acclaimed Ten Pound Poms. But it’s his work with Harlan Coben’s Netflix thrillers that propelled him into the international spotlight.
-
Fool Me Once (Netflix, 2024) starring Michelle Keegan and Richard Armitage, was a critical and streaming hit.
-
The Stranger and Stay Close also showcased Brocklehurst’s uncanny ability to juggle multiple timelines, secrets, and shocking reveals while keeping audiences emotionally hooked.
When ITV announced that Brocklehurst was stepping away from adaptations to create an original story about tangled family lives and forbidden love, industry insiders sat up straight.
“This is the drama Danny has wanted to write for years,” an ITV exec explained. “It’s personal, it’s raw, and it digs into the human psyche in a way we haven’t seen since the early days of Doctor Foster.”
The Plot: Two Families, One Dangerous Secret
At the heart of Adultery is 15-year-old Jess, a teenager caught in the throes of first love with her classmate Ollie. Their romance is innocent yet intense, a classic portrayal of young passion that feels like it could consume the world. But in the shadows of their teenage affair lies an adult entanglement far more dangerous.
Jess’s father, Tom, crosses paths with Ollie’s mother, Beth, under unexpected circumstances. What begins as a fleeting encounter spirals into a full-blown affair, dragging both families into a whirlwind of betrayal and deception.
According to ITV’s synopsis, the drama explores not just the consequences of Tom and Beth’s choices but also deeper themes:
-
Class divisions between the two households.
-
The lingering grip of grief, as both parents are wrestling with personal tragedies.
-
The invasive role of social media, which magnifies mistakes and exposes secrets in an age where nothing remains private.
The question pulsing through every episode is simple yet devastating: Can Tom and Beth resist their desires, or will they destroy everyone around them?
Themes: Why Adultery Matters Now
Adultery as a subject matter is nothing new in fiction—but Brocklehurst’s version is loaded with modern urgency.
-
The Intersection of Love and Technology
Social media is expected to play a huge role in the series, particularly in how teenage relationships and adult indiscretions bleed into the public eye. Imagine secrets that once stayed buried now going viral in seconds—an element critics believe will make the show painfully relatable. -
The Cyclical Nature of Desire
By paralleling Jess and Ollie’s teenage love with Tom and Beth’s adult affair, the show highlights how desire and recklessness cut across generations. -
Class and Grief
Reports suggest that both families are grappling with recent losses, adding emotional weight to their choices. The tension between privilege and struggle will sharpen every betrayal.
“Danny isn’t just writing about sex and lies,” a TV critic noted. “He’s writing about how people fill the voids in their lives—with love, with danger, with secrets. That’s what will hit home for viewers.”
Cast: Who’s Involved?
While ITV has kept much of the official cast under wraps, Digital Spy broke the news that Romola Garai (Vigil, The Crimson Petal and the White) has been spotted filming in Manchester for the series.
Alongside her, Andrew Knott (Protection, Ackley Bridge) was also photographed on set, sparking speculation about their roles.
Insiders believe Garai may be playing Beth, the mother whose affair triggers the story’s central conflict, while Knott could be stepping into the role of Tom, the grieving father pulled into a dangerous spiral of passion.
Fans are now eagerly waiting for announcements about the teenage leads, Jess and Ollie, whose chemistry will be pivotal to the show’s success.
Behind the Scenes: Production Buzz
Filming is currently underway in Manchester, with location shoots capturing both the intimate interiors of family homes and the bustling public spaces where secrets risk exposure. The show is being produced by Poison Pen Productions in collaboration with ITV Drama, with Brocklehurst himself serving as both writer and executive producer.
Crew members have teased that the cinematography will have a “gritty realism”, echoing the grounded style of Happy Valley while layering in the taut suspense of a Netflix thriller.
When Will Adultery Air?
No official release date has been announced, but given that production is ongoing, industry observers expect the series to premiere in mid-to-late 2026. ITV has confirmed that Adultery will air on ITV1 and STV, with streaming available on ITVX and STV Player.
Critical Hype: Britain’s Answer to Coben?
The comparisons to Harlan Coben are inevitable—and intentional. Brocklehurst has often been called Coben’s British counterpart, and with Adultery, critics believe he may have crafted a homegrown thriller that can rival the American author’s global dominance.
“Harlan Coben stories are about ordinary people in extraordinary situations,” one TV scholar explained. “What Danny is doing with Adultery is the same—but he’s making it uniquely British, with class dynamics and raw emotional messiness that American thrillers often gloss over.”
Why Viewers Are Already Obsessed
Even before its premiere, Adultery has sparked intense online chatter. On fan forums and social media, debates rage over:
-
Will Tom and Beth’s affair be exposed in the first episode, or stretched out across the season?
-
How will the teenagers react when they realize their parents mirror their own reckless love?
-
Will the series end in tragedy or redemption?
The consensus? Adultery is poised to be 2026’s most binge-worthy British drama.
Broader Context: ITV’s Bold Move
ITV has been steadily pushing back against the dominance of Netflix and Amazon by investing in gritty, character-driven dramas. Shows like Mr Bates vs The Post Office and The Long Shadow have proven that British networks can still deliver prestige television that grabs headlines and sparks national conversations.
By handing Brocklehurst free rein to tell an original, taboo-challenging story, ITV is signaling its ambition to dominate watercooler conversations once more.
Conclusion: Why You Can’t Miss It
With its combustible mix of teenage romance, adult betrayal, and the looming specter of social media exposure, Adultery isn’t just another family drama. It’s a mirror held up to modern Britain, reflecting the passions, pressures, and pitfalls of contemporary life.
As Danny Brocklehurst himself put it:
“Love and sex have the capacity to lift us to the highest highs and the lowest lows. This series is about both.”
If early buzz is anything to go by, ITV’s Adultery could be the drama that defines 2026—messy, addictive, and utterly unforgettable.
