Brand new police drama Blue Lights is now available to watch in full on BBC iPlayer, helping viewers looking for that crime series fix after the end of both Happy Valley and The Gold.


The new drama is set in Belfast and focuses on a group of rookie recruits working in the Police Service of Northern Ireland, with creators Declan Lawn and Adam Patterson previously saying its exploration of the political unrest in the area is "so important" following the real-life shooting of an off-duty police officer.

The six-part series stars Siân Brooke, Katherine Devlin, Nathan Braniff and Richard Dormer amongst others, with Brooke having taken on the role in part because her father was a police officer for a long time.

But when will episodes from the series be airing on BBC One, what is it about and who else is in the cast? Read on for everything you need to know about Blue Lights.

The official synopsis for Blue Lights says: "Grace, a mother of a teenage boy, has made the decision in her 40’s 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, who struggles with the fact that her chosen path may mean having to leave everything she’s ever known behind, and Tommy, 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?"
