Starring Adrian Dunbar, Martin Compston and Vicky McClure as three officers in specialised anti-corruption unit AC12, Line of Duty became essential viewing for its twisting, unpredictable plots. The drama began in 2012 and more than tripled its audience by the time series 5 aired, on BBC1, in 2019.

Where can I watch Line of Duty?

The first four series are available on Netflix. The fifth season is available on Amazon Prime Video. All five seasons are also available to purchase on DVD.

What is Line of Duty about?

Line of Duty differs from the typical detective drama in that the central characters, working together in AC12, are investigating other police officers. The idea of ‘the evil within’ adds to a plausibly sinister atmosphere that permeates through every season of Line of Duty.

Steve Arnott and Kate Fleming work together on the ground, often with Kate undercover, while boss, Superintendent Ted Hastings, looks on from headquarters. Many plotlines hinge on the idea that, because of their day to day jobs and understanding of criminal evidence, a bent copper is much harder to catch and convict than a normal criminal.
