The documentary, which is narrated by Sheridan Smith, takes a detailed look at the case from Julie's disappearance in 1989 until the murderer was retried and jailed for life in 2006, becoming the first person convicted under the changed law.

Featuring exclusive interviews with Ann, her family and friends, retired police officers, and other key individuals close to the story, the documentary will also include rare archive and images that tell the story of one mother's unwavering resolve to get justice for her daughter.

The documentary shows Ann's extraordinary campaign, her unshakable determination, and how her fight for justice has since helped secure other landmark convictions, including those of Stephen Lawrence's killers.
