Among France's top lawyers, Gloria Mendoza is a legend. She made a name defending mobsters before widening her list of clients to include ordinary citizens involved in crimes of blood. She won every case, earning the disapproval of the Bar Council for her loose ways with the code of ethics, and became known as "The Devil's Advocate". Now retired, Gloria is convinced there's a link between the deaths of a 15-year-old girl and her daughter.
