The northern suburbs of Atlanta, Georgia are normally a calm and idyllic place to live. The crime rate there is much lower than in many other places. But recently, the murder rate has increased considerably: finding out why is the job of Detective Sgt. Nick Watson. Nick is the homicide detective investigating the murders, but he is at a dead end. There is no evidence at any of the crime scenes: no DNA, no finger prints, no witnesses, nothing. Finding out why is Nick's first priority.
