Blue Lights

Blue Lights is a Northern Irish police procedural television drama series set in the present day and based at the fictional Blackthorn police station in Belfast, Northern Ireland. Created and written by Declan Lawn and Adam Patterson, the series was filmed in Belfast and directed by Gilles Bannier. It began broadcasting on BBC One on 27 March 2023.

The first series followed three probationary police officers of the Police Service of Northern Ireland (PSNI) and the experienced officers who train, mentor, and work with them. The second followed the same characters a year later as they tried to quell a loyalist feud in the city. Both series received critical praise and high viewership. A third series aired on 29 September 2025 and a fourth series has been commissioned by the BBC.

Three probation period rookie police officers in the Police Service of Northern Ireland are assigned to Blackthorn Station in Belfast. One of the new officers, Grace, is a mum in her 40s, who left her job as a social worker to join the Police Service, but only weeks into the job she wonders if she's made the right decision. Her fellow rookies are Annie and Tommy, who themselves are struggling under the immense pressure of the job. Facing criminal gangs and divided communities, they don't know who to trust. The odds are, they won't all make it.
