Will there be more series of Blue Lights?

Before series two had even landed, BBC bosses confirmed a third and fourth series of Blue Lights has been commissioned!

Sharing the news online in February 2024, bosses wrote: '🚨 Blue Lights series 3 and 4 CONFIRMED! The BBC has ordered two more six-part series of the critically acclaimed Belfast-based police drama'. (sic)

Lindsay Salt, BBC Director of Drama said: “We were bowled over by the reaction to Blue Lights and I’m really pleased to be confirming our commitment to bring two more series of our beloved Belfast drama to air. Adam and Declan have brilliant ideas about where to take the characters next and I can’t wait for viewers to see what’s in store.”

No further information for series three and four has been announced.

What is Blue Lights about?

Series one of Blue Lights follows three rookie police officers (Siân Brooke, Katherine Devlin, and Nathan Braniff) working in Belfast, attempting to fight crime and navigate life in a uniquely dangerous place to be a police officer.

Main character Grace, portrayed by Doctor Foster actress Siân Brooke, decides to leave her stable job as a social worker to join the police force, whilst being a mum to her teenage boy in her 40s.

The BBC say of the series one plot: '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?'

Trailer for Blue Lights:

A 30-second long trailer was released for series one of Blue Lights on Wednesday 15th March 2023, with the caption: 'Coming soon'.

What will series 2 be about?

Speaking in February 2024, bosses say of the second series: 'Grace, Annie and Tommy are growing up fast as police officers, but nothing can prepare them for the turmoil they face every day.

'It’s a year since the fall of the McIntyre crime gang and the vacuum has been filled by rival gangs, all competing for dominance. Constable Shane Bradley is drafted in to help, but his motivations are unclear. Tommy is dangerously seduced by the world of intelligence policing, while Grace struggles to deal with her son’s absence, and growing feelings for fellow officer Stevie. As a young loyalist threatens to take over the city, the officers face a major gangland feud – culminating in a violent and devastating confrontation.'
