About Line of Duty

Line of Duty follows AC-12, an anti-corruption unit tasked with the dangerous and thankless job of catching bent coppers. What begins as a procedural about rooting out individual rotten apples slowly mushrooms into something far larger: a sprawling conspiracy linking organised crime, institutional cover-ups, and a faceless mastermind known only as H. Every season tightens the screws, and nobody, however senior, is above suspicion.

Jed Mercurio built the show around a deceptively simple weapon: the interview room. The series is famous for its marathon interrogation scenes, where suspects sweat under fluorescent lights, caution tapes whir, and a single slip of the tongue can unravel an entire alibi. The acronyms fly thick and fast, the betrayals land like body blows, and the question of who can truly be trusted keeps viewers second-guessing right up to each finale.

Across six gripping series the drama became appointment television in Britain, drawing record audiences and sparking nationwide guessing games about the identity of the corrupt officers at its heart. Anchored by the dogged partnership of DS Steve Arnott and DI Kate Fleming, and presided over by the morally unbending Superintendent Ted Hastings, the show stars Martin Compston, Vicky McClure, and Adrian Dunbar.
