A mother's story behind one of the most dramatic true crime cases in recent history.

'I have lived every parent's worst nightmare. On what would have been my daughter's 29th birthday, Detective Superintendent Stephen Fulcher knocked on the door and told me my beautiful Becky was dead. Found buried in a shallow grave in a remote field, Becky had been brutally murdered.'

When Becky Godden-Edwards was killed, her mother Karen awoke to a world where the truth was never guaranteed; where taxi driver Christopher Halliwell got away with murder and the police officer who found her daughter was punished instead.

This is Karen's story. Despite unimaginable tragedy, her love for her daughter has been unbreakable: from her despair through Becky's troubled teenage years, to the agonising eight years when Becky was missing, and then the dramatic story of how a killer's confession led to a terrible discovery.

The one constant has been Karen's determination to fight for Becky, tirelessly campaigning for the truth about what happened to be heard and for Halliwell to face the consequences of his evil actions.
