The Murder Detective - Season 1

What begins as a murder investigation becomes a seven-year-long mission to identify those responsible, secure justice for Lyra's family, and take on the organisation that claimed responsibility for her death: the New IRA. Senior Investigating Officer Jason Murphy and his team begin the hunt for a masked gunman who seems to have disappeared without trace. With the murder weapon missing and not one of the 150 people on the street when Lyra was killed willing to come forward, detectives must painstakingly uncover the truth of what happened for themselves. Lyra's sister Nichola struggles with the devastating loss. As detectives uncover new evidence, the search for a single gunman grows into something much bigger, drawing Murphy towards investigating the leadership of the New IRA.

Murphy and his team recover a gun that may be linked to Lyra McKee's murder. A DNA lead gives detectives their first direct route into the network surrounding the killing. Drawing on forensic evidence, intelligence, CCTV and mobile phone footage, detectives believe they can finally put a name to the masked figure at the centre of the case. Murphy launches a series of high-risk operations targeting those suspected of involvement. The stakes are immense. As the hunt enters a decisive new phase, Lyra's family's agonising wait for answers continues.

After years of investigation, arrests and painstaking evidence-gathering, lead detective Jason Murphy is ready to make his boldest move yet. Convinced that those responsible for Lyra's murder reach far beyond the gunman, Murphy targets the figures who he believes sit at the heart of the organisation behind the attack. With unprecedented access to never-before-seen tactical operations, cameras capture the high-stakes effort to turn years of intelligence and evidence into charges. Murphy's team execute a series of coordinated arrests but are faced with a wall of silence. The investigation gathers momentum with a gripping and emotional finale to an extraordinary seven-year investigation.
