Detective Superintendent Sandra Pullman and her unconventional team of ex detectives – Jack Halford, Brian Lane and Gerry Standing – reinvestigate more unsolved murders and cold cases with their characteristic conflicts over procedure and rules.
Blackmail, conspiracy and cover-ups face the team when they reopen cases involving the suspected suicide of a witness to an air crash outside an American military base, the suspicious death of a drug addict in rehab, a pleasure cruiser disaster on the Thames, the murder of a film producer, the disappearance of a young political activist and her boyfriend, and the death of a timeshare magnate.
Alongside the cases, Lane finally agrees to treatment for his drink problem, Halford gets another chance to confront his nemesis Ricky Hanson and Standing gets asked out on a date which could be too good to be true.
Halford and Lane enter the world of "mixed economy policing" – i.e. everything they hate about the modern force – when they are temporarily seconded to the Murder Investigation Team.
The series is produced by Wall to Wall.
