Atlanta, Georgia. Present day. A young woman is brutally attacked and left for dead. The police investigate but the trail goes cold. Until a chance assignment takes GBI investigator Will Trent to the state penitentiary, and to a prisoner who says he recognises the MO. The attack looks identical to the one he was accused of eight years earlier. The prisoner’s always insisted that he was innocent, and now he’s sure he has proof. The killer is still out there.
