Line of Duty follows AC-12 – the Anti-Corruption Unit of the fictional territory of the Central Police Force. Their Role is to investigate public servants within the police force where any sign of corruption is present. The overarching Plot throughout the lifetime of the show is AC-12 discovering relationships between organised Crime Groups and Serving Police Officers.

There are three main characters that the series focuses on, DS Steve Arnott, DC Kate Flemming and their superior DSI Ted Hastings.

Arnott transferred to AC-12 after he refused to corroborate with a coverup of a shooting of an innocent member of the public during a raid on a suspected terrorist property. Flemming, initially a detective constable, is a chameleon when it comes to infiltrating other police units undercover in order to investigate suspects from the inside.  Hastings recruited both Arnott and Flemming due to their skills and integrity, Hastings was once a member of the Royal Ulster Constabulary in Nothern Island.

The show is full of twists and turns that send shockwaves through the storyline. Available on BBC iPlayer the programme is binge-worthy and in fact hard not to.
