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.”
