Detective Superintendent Sandra Pullman (Amanda Redman) is back heading up her team of retired detectives who don't always do things by the book but always get results.
This season Sandra has a new recruit, former DI Steve McAndrew (Denis Lawson), who is a bundle of energetic optimism with a tendency to get under the skin of the cases he's working on.
Breaking rules and ignoring procedure are all in a day's work for Pullman's team but even by Gerry Standing's and Brian Lane's standards, Steve's unorthodox approach to policing raises a few eyebrows.
In the first episode of the new season, Jack Halford deals a devastating blow to UCOS, he's quitting. But before the team - Detective Superintendent Pullman, Brian Lane and Gerry Standing - can question the reasons behind his decision and persuade him to stay, shadowy Whitehall Intelligence figure Stephen Fisher arrives with one of his secret cases, the unsolved murder of a woman dating back 100 years, giving them just 24 hours to solve it.
Will the team manage to change Jack's mind?
