Preceding the opening credits: "During 1953 and 1954 Pauline Yvonne Parker kept diaries recording her friendship with Juliet Marion Hulme. This is their story. All diary entries are in Pauline's own words."
Preceding the end credits: "In the hours following Honora's murder, a police search of the Rieper house unearthed Pauline's diaries. This resulted in her immediate arrest for the murder of her mother. Juliet was arrested and charged with murder the following day. After Pauline's arrest it was discovered that Honora and Herbert Rieper had never married. Pauline was therefore charged under her mother's maiden name of Parker. In August 1954, a plea of insanity was rejected by the jury in the Christchurch Supreme Court trial, and Pauline Parker and Juliet Hulme were found guilty of murder. Too young for the death penalty, they were sent to separate prisons to be 'Detained at Her Majesty's Pleasure.' Juliet was released in November, 1959 and immediately left New Zealand to join her mother overseas. Pauline was released two weeks later but remained in New Zealand on parole until 1965. It was a condition of their release that they never meet again."
