Here’s what you need to know about Blue Lights season 2, including the start date, plot and its new and returning cast.

What is the plot of Blue Lights season 2?

Set exactly a year after the dramatic conclusion of season 1, Grace, Annie and Tommy are no longer rookies. They face a whole new set of challenges as they mature as police officers.

The fall of the McIntyre gang has opened up a vacuum inside which rival gangs are competing for dominance – making police work more difficult than ever.

When a young loyalist threatens to take over the city, an explosive situation arises. A major gangland feud is in the making, which could have devastating consequences for everyone.

Meanwhile, Tommy takes an interest in intelligence policing, while Grace struggles with her feelings for Stevie.

Who are the new cast?

There will be a few new faces amongst the regulars. Frank Blake will join the cast, alongside Seamus O’Hara, Craig McGinlay, Seána Kerslake and Dan Gordon.

Frank Blake will portray new Constable Shane Bradley, an enigmatic new officer drafted in to help with the volatile gang situation. Not a stranger to playing a Constable, Frank’s first big role was as Constable Pip Bircher in The Frankenstein Chronicles in 2017. He played Alan, the abusive older brother of Marianne (Daisy Edgar-Jones) in Normal People in 2020. Since then, he’s starred as Captain Declan Fraser on Sanditon (2022) and Sean Maguire in Blackshore (2024).

Seamus O’Hara will play Lee Thompson. Seamus’ previous gigs include Line of Duty (2017), Game of Thrones (2019) and Shadow and Bone (2023).

Craig McGinlay (You) portrays Lee’s right hand man, Craig. Seána Kerslake (Bad Sisters) is his sister Mags, while Dan Gordon (Bloodlands) is their uncle Rab.
