This exclusive documentary follows the culmination of a 32-year fight for justice in a notorious unsolved double child murder. On 9 October 1986, nine-year-old friends Karen Hadaway and Nicola Fellows went out to play and didn't come home. The whole estate turned out to look for the two girls only to have their hopes dashed when they were found lying dead in undergrowth in Wild Park, on the outskirts of Brighton. Both had been strangled and sexually assaulted. This documentary follows police and scientists using cutting-edge methods as they attempt to uncover enough new evidence for the CPS to pursue a fresh prosecution against Russell Bishop - who was acquitted of the murders in 1987 - and charts the journeys of the families of Karen and Nicola as they try to find justice for the girls.
