Rosemary, a beautiful disturbed murderer at the centre of this powerful cocktail of family saga and crime drama which spans nearly thirty years. The story opens in London in the present day with a tense kidnap drama which leads to tragedy. Gradually a dark past and a childhood surrounded by people who could have saved her or stopped her earlier is revealed - and we witness the terrible consequences of their choices. Each episode rewinds back a decade earlier in this haunting tale of the making of a murderer - from adult, to teenager to toddler. David Byfield, an Anglican vicar and Rosemary's father; he blames himself for her evil, but must learn that he was not the only one to contribute to her nurture as she grew up. Family friend Wendy holds the key to the roots of Rosemary's problems and the very beginning of her descent into murder. Only by tracing events backwards through time can the truth be pieced together. A gripping and unsettling journey ensues, as we strip away layer after layer of a sociopath's history to discover the truth inside Rosemary's twisted mind and her sick soul.
