Around the autumn of 1964, married teenagers David and Maureen Smith, who live in the Gorton district of Manchester, have just become parents to their first child - a baby girl called Angela.

Tragedy strikes when Angela dies of cot-death at the age of six months, and Maureen turns to her older sister, Myra, for comfort, while David finds friendship in Myra's boyfriend, Ian Brady. David and Maureen know nothing of the secrets harboured by Brady and Hindley.

By Christmas 1964, Hindley and Brady have moved with Hindley's grandmother Ellen Maybury, to a new council house: 16 Wardle Brook Avenue, on the Hattersley estate near Hyde, Cheshire. David and Maureen follow them to Hattersley soon after, their new home being a flat in a tower block called Underwood Court.

In the meantime, local police are seen discussing the possible fate of several missing local children and teenagers. 16-year-old Pauline Reade disappeared without a trace from Gorton in July 1963, with the police suspecting that she had run off with a boyfriend without informing her family. Pauline Reade was in fact a neighbour of Myra Hindley in Gorton, but since her disappearance most of the local residents have been rehoused to other districts of Manchester and neighbouring towns, in order to allow for the demolition of the Victorian slums.

12-year-old John Kilbride had disappeared from nearby Ashton-under-Lyne in November 1963, and in June 1964 another 12-year-old - Keith Bennett - went missing from Longsight, a district in the south of the city. Despite months of searching, not a clue to the fate of either child is found. At least one police officer believes that the two disappearance are linked, but his theory is rubbished by a colleague. Keith Bennett's step-father is questioned several times, but his disappearance remains a mystery. John Kilbride's father faces accusations from members of the public that he murdered his own son, but the police do not believe that this is the case, and have no evidence to lead them to a suspect or a solution to their case.

On Boxing Day 1964, 10-year-old Lesley Ann Downey disappears after visiting a fairground near her home in Ancoats. It is not long before local police are speculating that her disappearance is linked to the earlier cases, while in the meantime her step-father is treated as a suspect and taken in for questioning more than once, but once again the disappearance remains a mystery.

Soon after moving to Hattersley, David and Maureen discover that they are having another baby. They are also faced with the threat of eviction from their new council flat for rent arrears, and David turns to Ian Brady for a solution. They plan a bank robbery, but on 6 October 1965 Brady and Hindley lure a strange teenager back to their house, with Brady pledging to rob him. David Smith witnesses Brady killing the stranger with an axe in the lounge of their house; the victim is a 17-year-old, Edward Evans, an apprentice electrician from Ardwick.

After the murder, and fearing for his own life, David helps clean up the mess and stays at the house until the early hours of the morning. When he returns home and tells Maureen about the crime, she finds his story hard to believe - particularly the claim that Myra was actively involved. In the morning, however, the couple go to the police, and Brady is swiftly arrested. Brady admits to the murder of Evans but insists that Smith was a willing accomplice. There is no evidence to implicate Hindley, so she walks free from the police station, despite David Smith's claims that she had helped lure Edward Evans back to the house to be murdered at Brady's hands. The police also allow Smith to walk free, despite Brady and Hindley both claiming that Smith was involved in the murder.

Meanwhile, police have found John Kilbride's name written in one of Ian Brady's notebooks, with one officer beginning to wonder if Brady is responsible for the disappearance and potential murder of John Kilbride, although senior officers dismiss this suggestion.

Ian Brady is in custody following his arrest, and has already admitted murdering Edward Evans. However, Myra Hindley is still at liberty, as police begin a murder investigation. David Smith tells police that he recalls Brady's claims that he has committed murders in the past, and buried the bodies on nearby Saddleworth Moor. Brady and Hindley claim that David Smith was also involved in the murder, but police also doubt that Smith was actively involved in the murder and he too has walked free. David and Maureen Smith are both taken to the moors by two officers in the meantime, in their attempts to jog their memories in hope of locating potential graves of murder victims.

Police first recover a notebook containing plans for the disposal of a body, and its content convinces them that Myra Hindley was actively involved in the murder of Edward Evans, and she is arrested on suspicion of murder.

In the meantime, the police search for bodies on Saddleworth Moor begins, and a suitcase believing to contain incriminating evidence is soon retrieved from a left luggage locker at a Manchester railway station. The suitcase contains numerous items, including photographs of Hindley and Brady on Saddleworth Moor. However, officers are even more horrified when they come across pornographic photographs of a young girl, believed to be Lesley Ann Downey. A reel-to-reel audio tape is also inside the suitcase, which plays out an audio recording of a young girl being sexually abused - the voices are identified as those of Brady and Hindley, and the girl is soon identified as Lesley Ann Downey. This evidence reduces a female officer to tears.

Following this discovery, David and Maureen Smith are taken in by police for questioning, but the police soon determine that Smith did not take part in any murders. Maureen was totally unaware of any of the crimes, and was only aware of her husband's plan to rob a bank with Ian Brady shortly after the murder of Edward Evans.

While questioning Brady and Hindley, the police read out the names of other missing children and teenagers who have recently vanished in and around Manchester. To most of the names, Brady and Hindley respond "Never heard of him/her", with the exception of one: Pauline Reade, who had been Hindley's neighbour in Gorton. Maureen Smith is also taken in for questioning after Brady and Hindley continue to insist that Smith was involved in the murder of Edward Evans, and was also present in the house when Lesley Ann Downey was being sexually abused. But they quickly realise that David and Maureen were not involved in the murders and were unaware of any of Brady and Hindley's crimes other than the murder of Edward Evans, and he and Maureen are free to return home.

The police soon find the bodies of both Lesley Ann Downey and John Kilbride, buried in shallow graves on Saddleworth Moor. They had been led to the grave of John Kilbride by a photograph of Myra Hindley and her dog standing on recently disturbed ground on the moors, identifying the location with a reservoir in the background.

Brady and Hindley are soon charged with the murders of Edward Evans, Lesley Ann Downey and John Kilbride, and remanded in custody to await trial the following spring.

The police also suspect Brady and Hindley of murdering other missing children and teenagers - including Pauline Reade and Keith Bennett - but have not recovered any bodies or other evidence to charge the pair with any further crimes. On 21 April 1966, Brady and Hindley go on trial at Chester Assizes, where they are greeted by a crowd of vigilantes who taunt them and hammer the side of the van transporting them to court. David Smith is the main prosecution witness, and Maureen, pregnant again, agrees to testify. The defence lawyer attempts to portray David Smith as a murderer, while Brady and Hindley deny the charges against them.

During the trial, Lesley Ann Downey's mother, Ann West, and stepfather, Alan, barge into David and Maureen's flat and attack them, believing that they were involved in their daughter's murder. David and Maureen's unborn child is unharmed, while Mr. and Mrs. West are cautioned by the police.

Brady and Hindley are convicted of the murders of Edward Evans and Lesley Ann Downey two weeks later. Brady is also convicted of the murder of John Kilbride, and Hindley is found guilty for being an accessory to that murder. Brady is sentenced to three concurrent terms of life imprisonment, while Hindley receives two life sentences for murder and a seven-year sentence on the accessory charge. The birth of their second child soon after the trial does nothing to alleviate public hostility towards David and Maureen, who soon find "Hindley Bitch" painted on their front door and are frequently verbally abused by neighbours. They have a visit from a senior officer who worked on the case, thanking them for helping bring Brady and Hindley to justice, and urging them to get on with their lives now that the trial is over.

By 1971, Maureen is living alone in a Manchester bedsit while David has served a prison sentence for wounding a man who provoked him in a pub with groundless claims that he had been involved in the Moors Murders. David and Maureen have had two more children. Unable to cope with being a single parent, Maureen has placed her children into care. On his release, David is able to get his children back, and moves away from Hattersley. Having initially turned against Maureen for standing by David over Myra, Nellie tracks her younger daughter down and the two reconcile.

Nellie convinces Maureen to visit Myra in Holloway Prison. Brady (who the trial judge felt had influenced Hindley into committing murder) has been imprisoned elsewhere. By now, having rediscovered her Roman Catholic faith, Myra, whose bleached blonde hair has now turned brown, tells Maureen a day does not go by where she does not think about the suffering she helped bring on the children and their families, or the trauma Maureen has been through because of her. Myra also explains that people are always making excuses for her behaviour, such as the beatings from her father when she was herself a child. But Maureen says he used to beat her too, and she didn't do what Myra did. Myra also says some people say Ian Brady corrupted her, and that she has decided to sever all contact with him.

David is not pleased when he learns that Maureen has been to see Myra, but Maureen argues that Myra has changed, although David is not convinced by Maureen's claims that Myra was bullied and blackmailed into taking part in the murders by Ian Brady. David is also convinced that Brady and Hindley were responsible for the murder of Pauline Reade, whose disappearance is still a mystery nearly a decade after she was last seen alive. Maureen also mentions that Myra could soon be released from prison on parole.

David and Maureen then turn their thoughts to their children and agree to patch up their differences for the children's sake. In the last scene, Maureen leaves the house. For a few moments, she stands on the doorstep, fighting back tears, and then she walks away from the house. Maureen is last seen walking down a street as the screen fades to black.

An epilogue follows, revealing the fates of Maureen, David, Brady and Hindley. Maureen died in 1980, aged 34, after suffering a brain haemorrhage; David remarried and had a daughter with his second wife; Brady is currently imprisoned at Ashworth psychiatric hospital in Maghull near Liverpool; and Hindley, aged 60, died in prison from a heart attack in November 2002 after 36 years in prison. By the time of her death, she was one of the longest serving prisoners in Britain.

The epilogue also reveals that in 1986 Brady and Hindley confessed to the murders of Pauline Reade and Keith Bennett. They were taken to Saddleworth Moor separately to help locate the bodies. Reade's body was found and buried in a proper grave, but Bennett's body was not. The drama ends with a tribute to the young victims.
