When she answers a call from an old friend, Dr Erin Taylor is catapulted into the drama of decades past. In 1996, three university students united to investigate the assault of a fellow student, Rina. But Erin and ‘The Furies’, as they called themselves, unwittingly triggered a time bomb. Two decades later, at a reunion lunch, Rina does not arrive. Within hours, Erin is missing as well, fighting for her life.
