What’s happened in Line of Duty?
The first series debuted in 2012 sees an innocent man getting killed after a counter-terrorist police unit raids the wrong flat.
After refusing to participate in a cover-up, DS Steve Arnott (Martin Compston) is recruited by Superintendent Ted Hastings (Adrian Dunbar), head of anti-corruption unit AC-12.
His first assignment with undercover officer Kate Fleming (Vicky McClure) is to investigate DCI Tony Gates (Lennie James), a high-flying officer with a suspiciously impressive success rate.
DCI Gates takes his own life – but the corruption does not die with him.
Another officer in his team, DS Matthew “Dot” Cottan (Craig Parkinson), is revealed to be an inside man for gangster John “Tommy” Hunter (Brian McCardle).
DI Lindsay Denton – as played by Bodyguard actress Keeley Hawes – led the drama in this season.
The character was involved in a police convoy ambush which lead to the death of some colleagues as well as a member of public who was under witness protection.
Denton dropped onto anti-corruption unit’s radar as it was revealed she was battling a debt problem.
But it does come with a twist, her motive wasn’t so much financial as it was covering up a bad decision that lead to the death of four colleagues.
This series saw officer Daniel Waldron investigated by AC-12 after a suspect was shot and killed.
But the first episode ended with the officer himself getting killed.
The unit uncovered a paedophile ring at Daniel’s old school involving some high-powered figures including Jimmy Saville.
It turned out that Waldron had been taking revenge on his previous abusers at the boys’ school.
But all the while, Dot was trying to stifle the case and stop it from coming out.
AC-12 turned their attentions to Roz Huntley (played by Thandie Newton) in this series.
They explored a potential miscarriage of justice when the pressure to close a case resulted in the wrong man – Michael Farmer (played by Scott Reid) – getting locked up.
It also saw the exoneration of Ted, Michael Farmer and Hana Reznikova who were unfairly implicated in the conspiracy.
Fleming, Arnott and Hastings unmasked Assistant Chief Constable Derek Hilton for his pivotal role in the series’ conspiracy.
They were convinced Hilton was the mystery ‘H’ who was complying with powerful criminals, but the finale ended with Hilton dying.
An Organised Crime Group (OCG) hijacked a police convoy transporting seized drugs and killed three armed officers; AC-12 suspect that undercover police may be involved.
They discover that the undercover officer is DS John Corbett and not, as originally assumed, Lisa McQueen.
The raid was masterminded by Corbett, who was posing as a criminal in order to identify the mysterious H.
Before Corbett can unmask H, he is betrayed by second-in-command Lisa McQueen (Rochenda Sandall) and brutally murdered.
The ensuing fall-out sees Ted Hastings suspended, investigated and charged with conspiracy by DCS Patricia Carmichael (Anna Maxwell Martin).
But, during a tense interrogation, Hastings turns the tables by exposing lawyer Gill Biggeloe (Polly Walker) as part of the OCG.
The series ends with Hastings back in charge at AC-12, after receiving a final written warning.
