Jed Mercurio’s hit police corruption drama Line of Duty
returns for it's fourth series with a brand new 6 part investigation.
A violent abduction in plain sight. An unsolved murder. A missing woman... and that's just the first episode.
This series sees Roz Huntley, played by Thandie Newton, a senior investigator on a career-defining case codenamed Operation Trapdoor. Three women are missing, presumed dead. Huntley is under extreme pressure to catch the culprit and prove herself to her superiors. She makes an arrest but is the suspect the right one?
plays forensic Investigator Tim Ifield who comes into conflict with Huntley when he raises concerns he has with her investigation. Does the evidence he's seen match the case the police are putting together? Or does Tim have cause for concern? He brings her methods to the attention of AC-12 for possibly tampering with evidence to nail the chief suspect.
Line of Duty has moved from BBC2 to BBC1 on Sunday nights at 9pm.
