Three former detectives thought they were retired-until the lovely and persuasive superintendent Sandra Pullman (Amanda Redman, Sexy Beast) recruited them to right the wrongs of the past. Now members of the unsolved crimes unit of the Metropolitan Police, they reinvestigate tough cases no one else can crack.

Their methods are old-fashioned, and they don't care about the rules because they have little to lose. Gerry Standing (Denis Waterman, The Sweeney) is thrice divorced; Brian Lane (Alun Armstrong, Bleak House) is depressed; and Jack Halford (James Bolam, The Beiderbecke Affair) is mourning the death of his wife, killed by a hit-and-run driver. But their camaraderie is real and their skills are still sharp. 8 episodes, 3 DVDs, approx. 480 minutes, SDH.
