The struggle that follows changes Abigail's life forever.

When the local police make a misjudgment that not only threatens the investigation but also places a young girl's life in danger, the case is handed over to Special Agent Will Trent of the Criminal Apprehension Team, paired with detective Faith Mitchell, a woman who resents him from their first meeting.

But in the relentless heat of a Georgia summer, Will and Faith realize that they must work together to find the brutal killer who has targeted one of Atlanta's wealthy.
