Television series
Between the Lines
Before Line of Duty, there was this: a slow-burn, unglamorous study of a Met detective whose job is investigating his own colleagues. Neil Pearson's Tony Clark is charming, careerist and quietly compromised, and the show treats police corruption as bureaucratic grind rather than thriller spectacle. Cold offices, grey mornings, moral rot creeping in sideways. Essential viewing for anyone who thinks institutional drama should feel institutional.

Line of Duty2012
Jed Mercurio's AC-12 is the direct descendant of Clark's CIB — the same claustrophobic interview rooms, the same sense that everyone including the hero is dirty. Faster, twistier, and utterly addictive.
But The plotting gets increasingly baroque and soap-operatic as it goes; the quiet realism of the original gives way to genuine melodrama.

The Shield2002
Vic Mackey is everything Tony Clark investigates, seen from the other side of the glass — a corrupt cop so magnetic you root for him anyway. Visceral, angry, brilliant television.
But American, punchy, and morally nastier than Between the Lines ever gets; if you wanted understatement, this isn't it.

Prime Suspect1991
Lynda La Plante's Jane Tennison shares Clark's exhausting battle against her own institution, fighting sexism instead of corruption but with the same slow, procedural grind and moral cost.
But Helen Mirren's Tennison is a tougher, more abrasive lead; some episodes lean harder into serial-killer horror than office politics.

The wildcard
Something you would not have found on your own.
Serpico1973
Between the Lines is fiction built on the exact real-world premise Serpico dramatised two decades earlier — a cop whose evidence against his own colleagues makes him the enemy inside his own force.
Al Pacino, mustache and all, plays the real NYPD officer whose testimony against departmental corruption effectively invented the genre Between the Lines belongs to. Furious, unglamorous, and true.
But It's a single two-hour film with '70s pacing, not a slow-burn series — you lose the accumulation Between the Lines relies on.

Cracker1993
Same era, same unglamorous Britain, same interest in the psychological wreckage crime leaves behind — Robbie Coltrane's alcoholic psychologist is as compromised as any CIB officer.
But It's about a profiler solving murders, not internal politics, so the institutional-corruption angle you liked here is mostly absent.

The Wire2002
Widen the lens from one man to an entire city and you get The Wire's vision of institutions failing from the inside — cops, docks, schools, politics, all rotten in the same specific ways.
But Five seasons is a huge commitment, and the Baltimore slang and sprawling cast take real patience to settle into.

State of Play2003
Paul Abbott's conspiracy thriller has the same appetite for institutional rot, swapping the police force for Westminster and journalism — the same sense that everyone answers to someone worse.
But It's twistier and more plot-driven than Between the Lines, closer to a thriller than a character study.

Bodyguard2018
Mercurio again, this time strapping the institutional paranoia to a bodyguard-and-principal thriller — propulsive, glossy, and built for a single hard weekend binge.
But It trades Between the Lines' patience for pure adrenaline; the politics are thinner than the pacing suggests.

Happy Valley2014
Sally Wainwright's Yorkshire copper carries the same weary, compromised authority as Clark, wrapped in a much bleaker family tragedy. Superb, unshowy performances throughout.
But It's less about internal police corruption than personal grief and small-town crime; the institutional angle is minimal.

Luther2010
If you want the atmosphere of institutional distrust with more style and less realism, Idris Elba's maverick detective operates just outside the rules Clark was built to enforce.
But It's pulpier and more serial-killer-of-the-week than anything in Between the Lines' bureaucratic world.

Michael Clayton2007
Swap the Met for a law firm and Clark for a corporate fixer, and you get the same moral shape — an insider whose job is protecting the institution starting to investigate it instead.
Same engine, different costume: a fixer inside a corrupt institution slowly realising he can't keep cleaning up other people's mess. George Clooney at his most quietly wrecked.
But No police, no procedure — it's corporate law, and the corruption is civil rather than criminal, so the stakes feel different.

The Seven Five2015
This is the real, uglier version of exactly what CIB investigates — a documentary confession from the kind of officer Tony Clark spent his career trying to catch, minus any institutional discretion.
A genuinely jaw-dropping documentary about Michael Dowd, the most corrupt cop in NYPD history, told largely by Dowd himself with zero remorse. Stranger and funnier than any drama could invent.
But It's trashy true-crime rather than considered drama, and Dowd's unrepentant charm can feel like the film is letting him off easy.
