The new series follows probationary officers Grace, Tommy and Annie as experienced officers become their colleagues and mentors; its return offers viewers of The Rookie another police procedural to watch.

Three years into their roles as response officers, the trio face a new threat linked to Northern Ireland’s drug pipeline, which police struggle to control.
