Plot
Set over a three-year period from 1983 to 1986, DCS David Baker leads an investigation of the vicious murders of the two Leicestershire schoolgirls, Lynda Mann and Dawn Ashworth. Alec Jeffreys at the time was an ambitious scientist who uncovered a remarkable method to read a person's unique DNA finger print. Convinced the murderer was local, Baker approached Jeffreys to utilise his scientific technique as a way to solve the murders. The first ever DNA manhunt and blood testing of many men followed – all in the aid of catching the killer.

The series premiered in Australia on BBC First on 19 September 2015.

Critical reception
The drama received a mixed reception. The first part was criticised for dramatic sluggishness and a reliance on crime-show clichés in the portrayal of the two main characters. The depiction of Alec Jeffreys as the stereotypical absent-minded "boffin" was cited by several reviewers. Gerard O'Donovan in The Daily Telegraph called the show's version of him a "stock obsessive boffin so wedded to his lab instruments that his marriage was permanently on the brink of collapse". Julia Raeside in The Guardian wrote, "There are obligatory scenes in which Jeffreys misses a school play and receives a phone call from his wife pronouncing, 'Your dinner’s in the dog.' There are only so many times co-workers can remark, 'Don’t work too late' or 'Aren’t you going home?' before the hammering repetition starts to cause a dent in your enjoyment." Chris Bennion in The Independent concluded that "Sadly this drama had the fingerprints of countless other by-numbers crime thrillers all over it."

Alex Hardy in The Times was less critical, giving the show four stars out of five and saying that "this fact-based drama managed to balance tragedy with optimism", but added that it "inevitably contained elements of soap".
