The H bomb

Line of Duty reaches a thrilling climax in a special feature-length finale…

- 

After epic curveballs, shocking deaths and tense interrogations, Line of Duty comes to an electrifying conclusion this week with a feature-length episode.

And there’s plenty of drama to pack in, especially with stalwart AC-12 boss Superintendent Ted Hastings (Adrian Dunbar) currently in custody after being arrested on suspicion of conspiring to murder undercover cop John Corbett (Stephen Graham).

Hastings claims he has been framed, but Detective Chief Superintendent Patricia Carmichael (Anna Maxwell Martin) is determined to prove that he is H, the corrupt police officer who has been liaising with a deadly organised crime gang. Will his dedicated colleagues DI Kate Fleming (Vicky McClure) and DS Steve Arnott (Martin Compston) fight to clear his name?
