FBI forensic artist Sydney Fitzpatrick questions the guilt of the man about to be executed for her fatheras murder twenty years earlier. The first stirrings of doubt occur when one of her forensic sketches on an unrelated case brings forth memories about her fatheras homicide that shead hoped to forget. A mysterious envelope arrives in the mail on the anniversary of her fatheras death. She opens the packet and discovers a blackmail letter written by her father, an old photo of his army buddies, and a deposit slip from a bank long closed. Refusing to believe that her father was involved in any blackmail scheme, she searches for evidence to clear his name. Her investigation leads to a trail of corruption by high-ranking US political officials, and a meticulous and deadly cover-up by the military and the CIA. The more Special Agent Fitzpatrick digs into her fatheras past, the more she finds it riddled with dark secrets and truths, including the fact that her fatheras seemingly ordinary military career was anything but stellar or even routine.
