Line of Duty - Series 4


Thandie Newton (Westworld, Crash) stars as DCI Roz Huntley in the fourth Series of Line of Duty.
In a career-defining case, Roz is under intense pressure from her superiors to apprehend a serial murderer after months of fruitless investigation. When a young man is charged doubts around is guilt lead the chief forensic investigator (BAFTA winner Jason Watkins) to AC-12. Is Roz ignoring forensic evidence that might prove the young man's innocence? AC-12's Supt Hasting (Adrian Dunbar) places DS Kate Fleming (Vicky McClure) undercover inside Roz's team and with DS Steve Arnott (Martin Compston) piling on the pressure from the outside, Roz is forced to act decisively. A mother of two and wife to Nick (Lee Ingleby, The A World), Roz will do anything to stop her life from unravelling. As suspicions mount and the case becomes ever more complex, AC-12 themselves come under threat.



As ever in this wilfully complicated, insanely gripping six-parter by Jed Mercurio - as close as Britain has recently come to old-school "water-cooler television" - meticulous police procedure was at the heart of everything, and the revelations came thick and fast. - The Telegraph.
