Blue Lights has been hailed as one of the "best TV series ever" as it made its comeback for a third season.
The acclaimed police drama's latest series kicked off on Monday (September 29), following two successful runs in 2023 and 2024. The BBC show's first episode saw the squad tackling a drug-fuelled party and orchestrating a drugs bust.
In another part of the show, tragedy struck at an upscale club with a man succumbing to an overdose, while officer Grace Ellis (Sian Brooke) faced personal turmoil upon discovering a girl she once cared for as a social worker was now in deep trouble, reports Belfast Live.

The fictional Blackthorn police station was the centre of attention, captivating viewers who took to social media platforms to laud the Belfast-based drama.
"Welcome back to without doubt one of the best TV series ever broadcast by the BBC," one viewer exclaimed on X, previously known as Twitter. "Blue Lights is simply magnificent."
Another fan expressed their excitement: "Here we go. One of the best shows of the year starting."
Echoing the sentiment, another added: "Damn, this is such a good show." "Great opener tonight," said someone else, adding: "Ramping the tension up already."

One comment read: "Shaping up to be a great season of Blue Lights. Great to have it back."
Another eager fan admitted they had "been waiting all year for this", while another shared that they were "SOBBING".
"What a series!" someone else praised, as another highlighted the "strong opening", which featured an intense chase sequence.
One fan confessed: "Binged watched series three of Blue Lights in half a day as I do every series. Gutted as now I have to wait. Roll on series four!"

The third instalment of Blue Lights follows the journey of response officers Grace, Annie (Katherine Devlin) and Tommy (Nathan Braniff), who have shed their rookie status at Blackthorn and are two years into their policing careers.
This latest season thrusts them into the grim realities of society's underbelly, where they encounter a world in which accountants and solicitors enable organised crime.
Simultaneously, new criminal factions have emerged to dominate the city's underworld.
Blue Lights airs on BBC One.
