The fourth series of the BBC police drama Blue Lights, set in Northern Ireland, has introduced explicitly topical storylines, including a race riot. The series, which premiered today, depicts police responding to an angry mob at a fete hosted by a refugee support centre.
The new season also explores themes of organised crime and institutional politics, with Blackthorn station reportedly facing closure due to insufficient metrics. Officers are also shown becoming involved in security-service operations.
The series continues to feature characters such as Grace, a former social worker, and introduces a new antagonist in the form of a racist influencer. A mid-season episode will include a flashback detailing the relationship between Gerry and Sandra, characters from an earlier season.
