The Walk-In, the 2022 British drama series, unravels the chilling true story of Matthew Collins – a former far-right extremist turned anti-fascist campaigner. Adapted from Collins’ memoirs and Robbie Mullen’s accounts, the five-part series exposes the inner workings of National Action, a banned neo-Nazi group that plotted to assassinate Labour MP Rosie Cooper in 2017. Collins’ journey from violent nationalism to becoming a key informant for Hope Not Hate forms the narrative spine, offering a visceral exploration of radicalisation and moral reckoning.
Stephen Graham’s Magnetic Gravitas
Led by BAFTA winner Stephen Graham (Boiling Point, Line of Duty), who also serves as executive producer, The Walk-In benefits from powerhouse performances. Graham portrays Collins with trademark intensity, balancing the character’s hardened resolve with flickers of vulnerability. His chemistry with Andrew Ellis (This Is England), who plays the impressionable recruit Robbie Mullen, anchors the series. Ellis masterfully depicts Mullen’s descent into extremism – a lost soul manipulated by ideologues – before his conscience triggers a perilous double life.
Dean-Charles Chapman’s Ice-Cold Fanaticism
The series’ most haunting presence is Dean-Charles Chapman (1917, Game of Thrones) as Jack Renshaw, the radicalised leader of National Action. Chapman embodies Renshaw’s “white jihad” ideology with unnerving stillness, his glacial stare underscoring a willingness to martyr himself for the cause. A scene where Renshaw calmly details plans to murder Cooper and a police officer chills to the bone, illustrating how extremist rhetoric metastasises into violence.
Blurring Fact and Fiction
Director Paul Andrew Williams (Murdered for Being Different) merges documentary realism with taut thriller pacing. Archival footage of real far-right rallies intercuts with dramatised safe-house meetings, creating a textured narrative that mirrors Black Klansman’s procedural grit. Oscar-nominated writer Jeff Pope (Philomena) avoids didacticism, instead letting contradictions simmer: Mullen’s initial thrill at belonging curdles into horror as he witnesses a member’s suicide and Renshaw’s assassination plot.
Nationalism’s Toxic Allure
The Walk-In dissects how groups like National Action prey on disaffection. Early episodes depict Mullen’s induction – a mix of camaraderie, conspiracy theories, and manipulated grievances. The series unflinchingly shows racist violence, including a brutal attack on a South Asian man, to underscore the human cost of dehumanising rhetoric. Yet it avoids sensationalism, framing extremism as a systemic failure rather than individual pathology.
A Mirror to Modern Fractures
Though set in 2017, the series resonates amid rising far-right activity across Europe. Collins’ transformation – from perpetrator to protector – speaks to broader themes of accountability and redemption. His work with Hope Not Hate, monitoring extremist groups, underscores the vigilance required to combat radicalisation. The series’ climax, reconstructing the MI5 sting that thwarted Cooper’s assassination, serves as a taut reminder of democracy’s fragility.
British Drama at Its Finest
With its lean five-episode structure, The Walk-In avoids the bloat of prestige TV, delivering a narrative as efficient as it is impactful. Cinematographer Carlos Catalan (The Crown) bathes safe houses in sickly yellows and interrogation rooms in sterile whites, visually echoing the moral chiaroscuro. A standout sequence juxtaposes Mullen’s panicked wiretapped calls with Collins’ methodical evidence-gathering, heightening the stakes of their precarious alliance.
Why It Demands Viewing
In an era where extremist ideologies proliferate online, The Walk-In offers neither easy answers nor comforting platitudes. Instead, it interrogates how hatred takes root – and the courage required to uproot it. Graham’s Collins emerges not as a saint, but a flawed man seeking atonement; Mullen’s arc rejects simplistic redemption, instead highlighting the grind of deradicalisation.
For audiences weary of simplistic “us vs. them” narratives, the series provides a necessary provocation: extremism isn’t a distant spectre, but a societal reflection. As Collins warns in the finale, “The fight never stops. You just choose which side you’re on.” The Walk-In ensures that choice feels anything but abstract.
