The trailer has been released for new BBC drama series Blue Lights.
Created and written by Declan Lawn and Adam Patterson, writers of The Salisbury Poisonings, the TV show follows three rookie police officers working in Belfast.
The six-part series is made by Two Cities Television and produced with support from Northern Ireland Screen as part of their continued partnership with the BBC.

Siân Brooke (Sherlock, Good Omens), Martin McCann (Marcella, Sentinel), Richard Dormer (Game of Thrones, Fortitude), Katherine Devlin (The Dig, Vikings) and newcomer Nathan Braniff lead the cast alongside John Lynch (Tin Star, The Fall), Jonathan Harden (Time, Unforgotten) and Valene Kane (The Fall, Gangs of London).
The BBC previously said: "Grace (Siân Brooke), a mother of a teenage boy, has made the decision in her 40s to leave her steady job as a social worker to join the Police Service of Northern Ireland. Having previously worked in social care she straddles a fine line between the personal and professional. It’s the biggest gamble of her life, and just a few weeks into the job, she’s making so many mistakes that her decision no longer looks like a winning bet.
"Her fellow rookies are Annie (Katherine Devlin), who struggles with the fact that her chosen path may mean having to leave everything she’s ever known behind, and Tommy (Nathan Braniff), who is desperate to prove himself, despite being disastrously inept at the practical side of frontline response policing.
"All three are new police officers in their probation period with the PSNI, the odds are at least one of them isn’t going to last. The pressure is immense, but if they succumb to it, they won’t survive. Often the rookie officers don’t know the extent of the peril they are in, or who they can trust.
"What’s it like to have to hide your job from neighbours, friends and even family? How do you distinguish between who needs your help and who wants you dead simply because of the uniform you wear?"
Siân Brooke previously said: “I am so thrilled to be playing Grace in Blue Lights. There is something incredibly special that Declan and Adam have crafted in these scripts and I was hooked from the very first page. Belfast is the beating heart of this piece and it’s a city I’ve been wanting to work in for a long time.”
Declan Lawn and Adam Patterson previously said: “Every writer wants to explore their own place, and their own society as authentically and as honestly as they can. We feel enormously grateful to BBC drama for letting us do that with Blue Lights. And to do it with a cast boasting so much new and established talent makes it even more exciting.”
This week, Declan tweeted: "Very excited for you all to see this now."
Blue Lights is produced with Gallagher Films.
You can watch Blue Lights on BBC One from Monday 27th March at 9pm. It will also be available on BBC iPlayer.
