Hannah Goldberg, Grace Valentine, and Kate Fitzgerald have been friends since they were boarders at an exclusive Catholic convent school in Melbourne's Toorak in the 1960s. As 16-year-old schoolgirls, they all had their first sexual experience with charismatic media personality, Atticus Ford. For the next thirty years, each woman continued to have a secret relationship with him that only ended when the sensational news of his disappearance in suspicious circumstances broke in the media.

When Atticus Ford's disappearance is re-opened as a cold case by the police, now treating it as a likely murder, complexities and tensions in the women's friendship emerge as, reluctantly, they reveal their secrets to each other.
