Murderer? Vigilante? Or just a devoted and desperate mother, driven to the brink of insanity by the powerlessness of the law? The story of Ellie Nesler raises many complex questions and she provoked a national debate in the US about the nature of justice when she walked into a Californian courtroom and shot twice-convicted child-molester Daniel Driver as he faced multiple child-molestation charges, including one relating to her own young son. Tracking the complex sequence of events both leading up to and subsequent to the killing this is the story of how Driver was deemed fit to work with children despite his paedophile tendencies, how he allegedly abused Elbe's son repeatedly, the trauma caused to children involved in abuse cases once they reach the courts, and how Ellie, a devout Christian, felt driven to drastic action through her fear that Driver would escape justice and destroy the lives of other children.
