After wrapping up in the UK on Nov. 3, Blue Lights Season 4 is finally making its way stateside.

The new installment of the Northern Irish police procedural will air on BritBox over the next six weeks.

Season 4 is set six months after the conclusion of Season 3 and continues an arc set up in the Season 3 finale as Helen McNally receives a promotion and takes charge of a classified, long-term intelligence operation designed to infiltrate Dana Morgan’s club and criminal network.

Per BritBox, here’s Season 4’s official snyopsis: “An explosion of unrest across the city challenges the section, while a series of back-room deals leaves Grace, Annie and Tommy wondering whether justice can ever really be done.”
