Winnie Johnson's search for the body of her son, Keith Bennett, who was murdered by Ian Brady and Myra Hindley in the 1960s. He is the only one of the five victims of the Moors Murderers who remains buried on Saddleworth Moor. Almost 50 years after Keith's disappearance, Brady still refuses to say where he buried the 12-year-old. Now 78 years old and recently diagnosed with cancer, Winnie refuses to give up her quest to find and bring home her eldest son and makes one last plea to Brady.
