1 :01x01 - Episode 1

The team reopen the case of young police cadet Kate Daniels, brutally murdered in 1987. Daniels had gone to a pub alone on the night she was killed and the only witness to the murder was a six-year-old girl, Patricia Lee. Now an optician, she tells Supt Sandra Pullman and Gerry Standing she still has a recurring nightmare about a man she saw running from the scene.

The finding of a gun in a cache of weapons trawled from a lake leads the team to petty criminal Philip Sheppard. Brian Lane and Jack Halford are trailing Sheppard as he stalks women, all petite and blonde like Daniels. Sandra admits she was at Hendon Police College with the victim and knew her personally.

Meanwhile, each team member seems to have a personal problem to deal with. Brian's delicate emotional balance goes into freefall when his wife leaves him - not helped by the fact that he has thrown his medication down the toilet. Gerry is also facing a shock in his personal life when he discovers he's going to be a grandfather, through his unmarried daughter Paula.

Back at UCOS, Brian becomes convinced that the case is connected to Nick Gilbert, another of Pullman's fellow trainees who was Daniels' lover but who dropped out. Gerry takes drastic action to help Patricia identify Sheppard in a line up, while Brian visits a still bitter Gilbert and, while he's not looking, swipes something from the house and takes it for forensic examination. Pullman is enraged at his actions and Brian is forced to confront how his obsession with the past is ruining his life. He decides to try to woo Esther back. But can Pullman confront her own past as a rookie copper and get the truth out of Gilbert?

UCOS is called to Buckingham Palace after a painting from the Queen's private collection is discovered to be a fake. The handsome Sir Tim, who oversees the collection, explains the investigation is top secret because his predecessor was found to have 'borrowed' paintings. Sandra doesn't want the case, but expert help is soon at hand when the aptly named Totty Vogel-Downing is seconded from art fraud to UCOS.

While Sir Tim tries - and succeeds - in charming Sandra, Totty discovers thumbprints on the canvases. Tests prove both fakes were painted in 1978 by an artist and political activist who committed suicide after a fire destroyed his studio. Old files suggest the fire could have been arson, aimed at a Kurdish sweatshop next door. Sandra and Jack visit a Bengali family who were injured in the blaze, while Gerry and Brian learn that remains of a white rat were found at the studio. The animal was too exotic to live in a warehouse naturally.

Jailed arsonist Pat the Rat says the rat must have been covered in petroleum jelly and used as a firebomb. Lists of clients from top London galleries link Pat to George Wilson, a notorious career criminal. Wilson escaped arrest 10 years earlier during Gerry's watch. When Deputy Assistant Commander Bevan blamed Gerry, the detective punched his superior - an offence that led to his early retirement from the force.

Sandra wants to contact Special Branch, much to the dismay of the paranoid Jack, Gerry and Brian.

To his alarm, Brian has no memory of Ed Koumas, an officer on the case. Gerry and Sandra visit an ideological Eleanor on her houseboat, while Brian revisits Frank who reveals Josh had a secret.

Worried about Sandra, they follow her, only to find her with a woman - her therapist. But on the way home, she is indeed followed by Special Branch officer Greg Johnson. She meets Greg, who admits his people moved Livesey's body and disposed of the murder weapon to save face, but still insists there was no conspiracy. He also tells Sandra he fancies her.

On the surface, Whitemead seems perfect, until one of the residents, Leonard, confides that the death a year previously of another elderly resident, his fiancée Maggie Newley, was covered up and passed off as suicide. Despite hearing this, and to Sandra's dismay, Grace sets her heart on moving in.

Since the alleged murder doesn't fall under her department's remit, but wanting to act in the best interests of her mother, Pullman is forced to turn a blind eye to her team's suggestion of an unofficial undercover investigation.

Jack Halford reluctantly agrees to play the role of an elderly relative and manages to secure a place for himself at the home. Like a thorn in Halford's side, Gerry Standing takes great delight in playing the concerned son visiting his old dad and, in an ironic twist, neurotic Brian Lane gets to play his doctor.

The chief suspect at the time, Marie's husband and owner of the security firm, Andrew Sinclair, continues to insist he is entirely innocent, but his story doesn't quite add up. A visit to the new owner of the security firm, Steve Palmer, doesn't provide Gerry Standing with records he was hoping to find, but it does result in Palmer making the cash-starved Standing an offer he can't refuse. Brian Lane looks into the dive clubs that would have had access to the lake over the years, which leads him to diving instructors Martin Viner and Trisha, but that appears to be another dead end.

Frustrated by the pace of the investigation, Pullman decides to make the dive herself to take a closer look at the van.
