Warning – this article contains full spoilers for Blue Lights season 1.


After a year's wait, viewers now finally know exactly when they will get to see the new season of hit BBC One police drama Blue Lights.

The first season was hugely popular with viewers, so much so that it led to the show being recently renewed for a third and fourth season, alongside the upcoming second run.

News of the release date for season 2 was revealed alongside an action-packed trailer, which gave us our first look at Grace, Stevie and the rest of the PSNI team in Belfast in the new episodes, which will be set one year after season 1.

But just when will the episodes air, who is returning from the cast and what will happen in the new season?

Filming on the season took place in summer 2023 in Belfast.

The official synopsis for Blue Light season 2 says: "In series two, 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."

The new season of Blue Lights will see most of the central cast returning, including Siân Brooke, Martin McCann, Katherine Devlin and Nathan Braniff.

Perhaps surprisingly, after she left the police force at the end of season 1, Hannah McClean's Jen Robinson is also among the returnees.

Of course, one cast member who won't be back is Richard Dormer, whose character Gerry tragically died in season 1. However, Gerry's wife Sandra will be back, once again played by Andi Osho.

Meanwhile, new cast members arriving in season 2 include Frank Blake (Sanditon), Seamus O'Hara (Dungeons & Dragons: Honour Among Thieves), Seána Kerslake (Smother) and Casualty legend Derek Thompson.
