Blue Lights is back for a second season. The BBC police drama gripped viewers with its debut season that followed three probationary officers in the Police Service of Northern Ireland, as they struggle with the high-pressure job. 

Led by Doctor Foster star Siån Brooke, Katherine Devlin and Nathan Braniff, it’s a must-watch for fans of crime dramas like Broadchurch, The Responder and Line of Duty.
