Blue Lights: The frightening true story behind BBC One police drama as it returns for series 4
The police drama tackles some of the biggest issues facing Northern Ireland today...
Blue Lights is finally back on our screens after what felt like a hellishly long wait for series 4 – and we can reveal that some of it is based on a true story.
Having first landed on our screens in 2023, the BBC One police drama subsequently became a firm favourite with fans. The Beeb has sold it in over 160 territories. And it’s won several prestigious awards (including a BAFTA for Best Drama).
Set in Belfast and following the Police Service of Northern Ireland (PSNI), viewers and critics have praised the show’s gritty realism. It’s just one of the many aspects that make the series so successful. After all, this is a drama that isn’t afraid to kill off a main character just after you’ll fallen in love with him. (R.I.P. Gerry Cliff)…
So you might not be too surprised to hear that Blue Lights is actually largely based on a true story and real events. Here’s what co-writers Declan Lawn and Adam Patterson shared with us.
Is Blue Lights series 4 based on a true story?
Police procedural drama Blue Lights is, and always has been, based on real problems that affect Northern Ireland today – and in its troubled past. And the current series 4 is no exception.
Series four picks up six months on from the end of series three, and feels very much like the second half of one story. Declan Lawn and Adam Patterson, who co-created, co-wrote, and executive produced the series, told us: “We tackle some of the biggest issues facing Northern Ireland today. These include racism, attacks on migrant communities, and pressures within the criminal justice system. It’s probably our boldest series yet.”
The new six-part series joins Constables Grace Ellis, Tommy Foster, and Annie Conlon three years into their jobs as response officers. They are operating at their limit, facing a new threat on the streets that the police can barely control.
The BBC adds: “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.”
‘Blackthorn Police Station faces closure in Blue Lights series 4’
Worryingly, viewers will see their favourite police station facing closure in Blue Lights series 4. And this is a very real problem in real life. Declan Lawn explains: “The station closure is inspired by real conversations with serving officers. Budget pressures mean stations are closing across Northern Ireland – some to be turned into luxury apartments. We wanted to explore what happens when a close-knit team faces being torn apart by its own organisation.”
Adam Patterson continued: “Lots of bureaucratic institutions are facing a reduction in staff, resources and support. But what happens when it hits the police service? Crime isn’t reducing, and you have the same job to do with less people? For Helen [played by Joanne Crawford] especially, it’s incredibly difficult. She’s trying to protect her officers, while keeping the threat hidden from them. And she’s about to find out that leadership becomes an increasingly lonely place.”
Blue Lights series 4: Elements of a true story are woven in
As well as facing staff closures, the Blackthorn coppers – or peelers as they are called in Belfast – also face the very real threat of attacks against migrant communities.
Declan Lawn told us: “When we spoke to serving officers, many told us this is one of the biggest challenges they face. We wanted to tell that story honestly and with empathy, showing different perspectives without losing sight of the human impact. We know from our research that crimes of racial hate against migrants is set to be the biggest issue for the police in the next 10 years. These are all things we’re grappling with as a community, as a society. If we can in some way illuminate why these things are happening through Blue Lights, then we’ve we’ve been successful storytellers.”
Adam Patterson added: “Each season reflects the issues affecting Belfast today, and this is one of the most urgent. Drama allows us to explore not only the events themselves but the emotions and tensions behind them.”
Blue Lights focuses on ‘what’s happening in the real world’
Siân Brooke plays Grace Ellis, who is more empathetic than most. The actress revealed the unifying themes of Blue Lights, saying: “The key themes of the show this series are human kindness and the theme of home and what that means to people. The writers are clever in how they weave elements of what’s happening in the real world with storylines from series one through to four.
“The writers don’t shy away from the seriousness of recent events in Northern Ireland. They’ve humanised those stories and taken a tough job such as policing and given it a heart too. They also don’t tell you what to think. The viewer has both sides of the story.”
Series 4 is ‘inspired by real events’
Talking about Blue Lights series 4, executive producers and co-creators Stephen Wright and Louise Gallagher explained what elements are based on a true story.
Stephen Wright said: “This year, there are two major storylines. One explores Belfast’s role as a transit route – a pipeline for organised drug trafficking into Great Britain and beyond, inspired by real events. The other centres on migration, reflecting issues currently affecting communities across Northern Ireland. We wanted this series to engage with contemporary stories as well as the legacy of the past.”
Meanwhile, Louise Gallagher explained why the series “presents policing through a human lens”. She concluded: “From the beginning, we’ve wanted to show the people behind the uniform. These are ordinary people doing extraordinary jobs, often carrying enormous emotional burdens.
“We’ve heard from many [real] police officers who felt the series reflected experiences they’d never spoken about before, and that’s been incredibly meaningful.”
