Having made its highly anticipated return at the end of September, the police drama will be airing new episodes every Monday for six weeks. The third episode will be broadcast tonight (October 13).

Blue Lights is set to be on BBC One at 9pm this evening. It is due to run for an hour and will finish at approximately 10pm.

The full boxset is available to watch on BBC iPlayer, for those who don’t want to wait a week between episodes.

The preview for tonight’s episode, via Radio Times, reads: “Grace and Shane push boundaries for Lindsay's sake as a threat closes in. Aisling and Tommy respond to a call-out where things are not as they seem, with unexpected consequences.”

Who is in the cast of Blue Lights?

Plenty of familiar faces will be back for the latest season of the Belfast-set crime drama. It includes all of the main rookie officers.

The full cast for series 3 includes:

  • Siân Brooke as Grace Ellis
  • Katherine Devlin as Annie Conlon
  • Nathan Braniff as Thomas Foster
  • Martin McCann as Stephen Neil
  • Joanne Crawford as Helen McNally
  • Hannah McClean as Jennifer Robinson
  • Andrea Irvine as Nicola Robinson
  • Frank Blake as Constable Shane Bradley (series 2-)
  • Andi Osho as Sandra Cliff

  • Cathy Tyson (Series 3)

The show has had one major departure so far with the character of Gerry Cliff (Richard Dormer) being killed in the first season.

What to expect from Blue Lights season 3?

Speaking about the upcoming episodes, co-creator Declan Lawn said: “Series three looks at the professional apparatus alongside organised crime, and how paramilitaries in Belfast are often in thrall to international organised crime gangs using the territory as a stopping off point for large scale drug smuggling. It also looks at sexual exploitation of kids in care. These storylines are entirely fictional but informed by careful research so have a real authenticity.

“Cathy Tyson plays Dana Morgan, a new powerful figure on the criminal side, and her nemesis within the police is Intelligence Department cop Paul Collins (Colly) who is played by Michael Smiley. In saying that, many of the regular characters are back and ready for action. We hope there are quite a few gripping moments, and a few emotional ones too. In this season our main characters go through some very difficult things.”

Grace’s actor Sian Brooke added: “When Declan (Lawn) was researching this series he said the police referenced the ‘two-year fade’ where the officers are hit by the reality of the job in terms of their hopes, dreams and the practical side of what they do. This is especially pertinent for Grace who wants to bring about change and is frustrated by the machinations of the organisation.”
