If you've got a Line of Duty shaped hole in your heart, have you been watching Blue Lights? And if not, what are you doing?! There's a season four on its way, and judging by the new trailer, they've managed to keep the thrill alive.
Blue Lights follows a group of new Police Service of Northern Ireland recruits in Belfast, who are chucked into the deep end on the job. Grace, Annie and Tommy are dealing with divided communities and criminal gangs, alongside their own personal struggles, as they attempt to fight crime on the front line.
Fans have been obsessed with the first three seasons, and now a fourth is on its way. Here's everything you need to know about it, from the storyline to a release date and cast.

As they grapple with big decisions about their future, Grace, Tommy and Annie must find the courage to face the greatest threat they have ever encountered: the truth."
