Declan Lawn and Adam Patterson, co- creators and co-writers say: “We’re very excited to bring this series of Blue Lights to audiences. It reveals a lot of dark secrets, examines what justice looks like in Belfast today, and ties together the past, present, and futures of Grace, Annie and Tommy in an action-packed story. We can’t wait to start filming it!”

Stephen Wright, Two Cities Television and Louise Gallagher, Gallagher Films say: “We are delighted to get the cast and crew back together for series four and welcome some new faces to the Blue Lights team. The appreciation for the show means so much to everyone involved and illustrates the power of fantastic teamwork.”

Nick Lambon, BBC Drama Commissioning Editor, UK & Northern Ireland, adds: “Blue Lights has gripped and entertained millions of viewers across three series and Declan and Adam’s scripts will once again have us all on the edge of our seats. Gerry Cliff was such an integral part of series one so to have Richard Dormer back alongside our talented cast is a dream come true. We are over the moon to be back filming in Belfast, and with so many twists and turns in store, fans of Blue Lights have plenty to look forward to.”

Three years into their jobs as response officers, Constables Grace Ellis, Tommy Foster, and Annie Conlon are operating at their limit, facing a new threat on the streets that the police can barely control. Meanwhile the murder trial of Gerry Cliff exposes a dangerous and long-buried secret that leads to chaos both inside the police, and across the criminal underworld. As they grapple with big decisions about their future, Grace, Tommy and Annie must find the courage to face the greatest threat they have ever encountered: the truth.
