Written by an ex Merseyside Police officer, BBC's new original show The Responder is billed as a "distinctive new take" on crime drama.
The show follows Chris Carson, a crisis-stricken, morally compromised, unconventional urgent response officer tackling a series of night shifts on the beat in Liverpool.
Chris is loosely based on former cop Tony Schumacher, and Martin Freeman, best known for The Office and The Hobbit, is said to have spent a year perfecting his Liverpool accent to give a realistic portrayal.
