In the rarefied air of modern television, where crime dramas jostle for supremacy like contrails in a crowded sky, few arrivals have landed with such immediate, gut-wrenching force as In Flight. Premiering on Channel 4 in mid-August 2025, this six-episode British thriller—starring the formidable Katherine Kelly as a desperate flight attendant plunged into the underworld—has ignited a firestorm of acclaim after just one episode. Critics and viewers alike are buzzing: “It’s like Breaking Bad crash-landed in a Bulgarian prison,” one reviewer quipped, capturing the show’s alchemy of everyday heroism twisted into high-stakes villainy. Where Walter White cooked meth in the New Mexico desert, Jo Conran smuggles it across international borders, her maternal instincts morphing into a razor-sharp survival instinct. But In Flight doesn’t just borrow from the blueprint; it amplifies the descent, layering in claustrophobic global intrigue, raw emotional shrapnel, and twists that make Vince Gilligan’s saga feel almost quaint by comparison. As the series hurtles toward its finale, it’s clear: this isn’t just a binge—it’s a nosedive into the abyss of family, fidelity, and the filthy compromises we make when the stakes are sky-high.

The premise hooks you faster than a faulty seatbelt. Jo Conran (Kelly), a 42-year-old single mother and veteran cabin crew member for a mid-tier airline, embodies the quiet grind of the working class: long-haul flights from Heathrow to exotic ports of call, snatched moments with her teenage son Sonny (Harry Cadby), and the lingering ache of a fractured past with her ex, customs officer Dom Delaney (Ashley Thomas). Life’s turbulence is manageable—until it’s not. On a routine trip to Sofia, Jo learns Sonny has been arrested for the brutal stabbing death of a local man during a backpacking bar brawl. The evidence is damning: fingerprints on the knife, witnesses placing him at the scene, and a swift guilty verdict in Bulgaria’s notoriously unforgiving courts. Sonny swears innocence, claiming a shadowy figure framed him amid a haze of cheap rakia and tourist traps. Jo believes him, of course—blindly, fiercely—but appeals drag on, and the specter of a 15-year sentence in a hellish Eastern European prison looms like a storm front.

Enter the villains: a transnational crime syndicate with tentacles in every airport lounge from Istanbul to Bangkok. Led by the charismatic yet chilling Cormac (Stuart Martin), a Irish-born enforcer with a silver tongue and a ledger of blood debts, the gang approaches Jo with a devil’s bargain. Smuggle their product—heroin-laced perfume bottles, ecstasy hidden in duty-free chocolates—on her flights, and they’ll pull strings to free Sonny. Refuse, and he’ll be shivved before lights out. It’s a classic hostage thriller, but In Flight subverts it from the jump. The first episode, “Layover,” doesn’t waste breath on exposition; it catapults us into Jo’s prison visit, the concrete walls closing in as Sonny begs through plexiglass, his boyish face gaunt with terror. “Mum, they’re gonna kill me,” he whispers, and in that moment, Kelly’s eyes—wide with a mother’s primal fury—become the series’ North Star. By episode’s end, Jo’s first run: a gut-clenching sequence at Istanbul Atatürk Airport where she palms a package past sniffer dogs, her uniform a deceptive shield in the sterile glow of security scanners. The reveal? The drugs aren’t just cargo; they’re a ticking bomb, laced with a volatile cutting agent that could detonate mid-flight if mishandled. Viewers didn’t just watch—they white-knuckled the remote, with social media exploding: “One ep in and I’m already addicted. Jo’s no Heisenberg, but damn if she isn’t cooking up trouble at 30,000 feet.”

What elevates In Flight beyond pulpy airport paperback territory is its unflinching dive into the moral rot beneath the glamour of global travel. Co-created and written by Mike Walden (Marcella, Whitstable Pearl) and Adam Randall (Slow Horses season 4), directed with taut precision by Chris Baugh (Wreck, Tin Star), the series transforms the skies into a metaphor for Jo’s unraveling life. Flashbacks punctuate the narrative like sudden downdrafts: Jo’s early days as a wide-eyed purser, falling for Dom amid layovers in Mumbai; the acrimonious split after his job’s endless overtime eroded their bond; Sonny’s rebellious streak, born of neglect and the lure of cheap adventure. These aren’t mere backstory—they’re pressure cookers, revealing how Jo’s “harmless” smuggling side-hustles (pilfered hotel toiletries for extra cash) primed her for the big leagues. As the episodes unfold, the operation escalates: Episode 2, “Red Eye,” sees Jo recruiting her sharp-tongued colleague Zara (Ambreen Razia), a fellow attendant with her own debts and a knack for sleight-of-hand, turning the cabin crew into an unwitting cartel cell. By Episode 3, “Turbulence,” they’re navigating a double-cross in Bangkok’s teeming night markets, where a botched handoff leaves Jo with a bullet graze and a conscience shredded like contrail vapor.

The cast is a masterstroke, each performance a pressurized cabin of tension. Katherine Kelly, the Coronation Street alum whose turn in Happy Valley proved her mettle in gritty realism, is revelatory as Jo. Gone is the soap-star poise; in its place, a woman fraying at the edges—nails bitten to stubs, voice cracking over satellite calls to lawyers, her flight attendant smile a brittle mask that crumbles in hotel bathrooms. “Jo isn’t a hero or a villain; she’s a mirror,” Kelly said in a pre-premiere chat, her Mancunian lilt underscoring the role’s roots in working-class resilience. “We’re all one bad layover from breaking.” Opposite her, Stuart Martin (Jamestown, Rebel Moon) slithers into Cormac with predatory charm: a wolf in wool, flipping from affable tour guide (“Fancy a pint, love?”) to stone-cold manipulator in a heartbeat. His chemistry with Kelly crackles—equal parts seduction and threat—evoking the toxic tango of Breaking Bad‘s Walt and Jesse, but laced with transatlantic menace. Ashley Thomas (Top Boy, Sex Education) brings brooding intensity to Dom, the ex whose badge makes him both ally and obstacle; their charged reunions in dimly lit airport bars pulse with unresolved heat, hinting at rekindled sparks amid the chaos.

Supporting players flesh out the web with nuance. Harry Cadby (Red Rose, Inside Man), a rising teen talent, imbues Sonny with vulnerable fire—less petulant rebel, more scared kid clinging to his mum’s phantom strength. Ambreen Razia (Black Mirror, Ted Lasso) shines as Zara, the reluctant accomplice whose wry humor (“Darling, if we’re doing this, at least get us first-class seats”) lightens the gloom without undercutting the stakes. Bronagh Waugh (The Fall) chews scenery as Melanie, Jo’s brittle sister-in-law harboring secrets that threaten to ground the whole op, while Corinna Brown (The Serpent) adds layers as Kayla, Sonny’s enigmatic girlfriend whose loyalties blur the line between love and leverage. Even bit roles pop: Charis Agbonlahor as the no-nonsense D.I. Shana Wright, sniffing corruption from afar, and Julia Brown as a wide-eyed rookie attendant unwittingly entangled in the web. Baugh’s direction—shot on location in Bulgaria’s stark prisons, Thailand’s humid alleys, and London’s fog-shrouded airstrips—amplifies the ensemble’s raw edges, with cinematographer Suzie Lavelle (Killing Eve) capturing the vertigo of mid-air dread in sweeping drone shots of hurtling jets.

Production buzz around In Flight was electric from the start. Filmed over four months in 2024 across Manchester (doubling for London hubs), Sofia’s grim outskirts, and Bangkok’s chaotic sprawl, the series—produced by Buccaneer Media for Channel 4 and Fremantle—clocked a modest £12 million budget but punches like a blockbuster. Executive producers Anna Burns, Tony Wood, and Richard Tulk-Hart championed its “high-wire act,” blending Narcos-style cartel kinetics with The Night Manager‘s espionage sheen. Walden and Randall, drawing from real-life airline smuggling busts (think the 2010s wave of cabin crew mules for South American cartels), infused authenticity: consultants from former BA staff advised on in-flight concealment tactics, while Bulgarian prison experts ensured the facility scenes’ harrowing verisimilitude—claustrophobic cells, corrupt guards bartering cigarettes for silence. “We wanted the glamour to curdle fast,” Baugh noted. “One minute, Jo’s serving champagne at 35,000 feet; the next, she’s gutting fish in a back-alley market to hide kilo bricks.” Post-production tweaks, including a pulse-pounding score by Ruth Barrett (The Salisbury Poisonings), ratcheted the tension, with sound design layering jet roars over whispered threats for an immersive ASMR of anxiety.

Reception? Stratospheric. Debuting to 2.1 million viewers on August 12—Channel 4’s biggest drama launch since It’s a Sin—In Flight has held steady at 1.5 million per episode, skewing young and female with its maternal fury. Rotten Tomatoes sits at 82% critics/78% audience, lauding its “palm-sweating propulsion” and Kelly’s “career-best ferocity.” The Guardian called it “a nerve-shredding watch,” praising how it “makes Breaking Bad‘s blue meth empire feel like a Sunday stroll.” Digital Spy dubbed the opener “brilliantly tense, unmissable—save for its one rushed thread,” while Radio Times hailed it as “the British thriller we’ve been grounded too long without.” Fan fervor on X (formerly Twitter) borders on evangelical: #InFlight trended UK-wide post-episode one, with posts like “Jo Conran just made Walter White look like a choirboy. Katherine Kelly OWNS this,” amassing 50K likes. Memes proliferated—Jo’s steely glare photoshopped over Heisenberg’s porkpie hat—while forums dissected parallels: both protagonists’ “just this once” mantras spiraling into syndicate sovereignty, but Jo’s arc skewers gender norms, her “mommy dearest” leverage a fresh twist on patriarchal power plays.

Yet In Flight isn’t content with homage; it interrogates deeper shadows. In a post-Brexit, migration-crisis world, it spotlights the underbelly of aviation’s “open skies” promise: exploited crews as smuggling vectors, corrupt border regimes preying on the desperate, and the invisible labor of women like Jo—overworked, underpaid, invisible until they snap. Episode 4, “Diversion,” pivots to outright savagery: a mid-series betrayal strands Jo in a Thai fishing village, where she witnesses a rival gang’s watery execution, forcing her to wield a harpoon in self-defense. The dirtiness peaks in Episode 5, “Final Approach,” as Dom uncovers the plot, pitting ex-lovers in a cat-and-mouse through Heathrow’s underbelly—vent shafts, cargo holds, a climactic standoff amid baggage carousels. Twists abound: Zara’s hidden agenda (spoiler-free: it’s personal, venomous), Sonny’s not-so-innocent backpacking fling, and Cormac’s fractured backstory, humanizing the monster without absolving him. By the finale, “Touchdown,” the series lands a gut-punch resolution—redemption laced with irreversible scars—leaving threads for a potential season two, as hinted by Kelly’s coy “Jo’s got more miles in her.”

In an era of glossy American imports, In Flight reclaims the British thriller’s edge: grittier, more intimate, unapologetically female-driven. It eclipses Breaking Bad not in scope but in intimacy—the horror isn’t empire-building, but a mother’s soul sold one pouch at a time. As Jo stares down the barrel of her choices in that final frame, uniform bloodied and eyes unblinking, you can’t look away. This isn’t TV; it’s a freefall into what we’d do for love. Buckle up—In Flight isn’t just hooked fans; it’s hijacked the genre, and there’s no safe landing in sight.
