Seventy-five years ago, a madman nicknamed the Torso Killer terrorized Cleveland, claiming dozens of victims. He was never caught. Today, forensic scientist Theresa MacLean is called to examine a decades-old body that everyone assumes is a lost Torso Killer victim. Though few clues still exist, Theresa sees this as an opportunity to shed some light on a mysterious piece of Cleveland's past. But then another body - this one recently deceased - turns up, and all clues point to a new Torso Killer. Suddenly, Theresa's investigation takes on an entirely different meaning. She has unwittingly opened a door to the past - a door someone wanted to keep closed - and Theresa soon finds herself nearer to danger than she ever could have imagined.
