Win Garano, rising star of the Massachusetts State Police, is sent to Tennessee by D.A. Monique 'Money' Lamont to investigate a murder that took place more than twenty years before. The calculating Monique thinks she has found the perfect mystery to showcase her new crime initiative and Garano has no choice but to follow her lead. Along with his colleague Sykes, Garano follows the evidence to a killer in Knoxville, and then back to Boston and a crime that hits much closer to home.
