DI Frost is an old-school, no-nonsense copper who believes in traditional policing methods. Frost uses what he knows about the street to find answers to crimes as a member of Denton's CID. His home life is complex, but his daily nemesis is the station's commander Supt. Mullett, who is constantly worrying. He doesn't appreciate DI Frost's rough-and-ready manner, which doesn't stop him from trotting him out--with his George Cross bestowed upon him.
