Rebecca Wallace is a woman who enjoys doing volunteer work with seniors. One day she is tragically mauled by a Florida panther. Orlando detective Bone Ramsey is called in because he is one of the last people to see Rebecca Wallace alive. Another deadly attack happens and Ramsey sees a lethal pattern emerging. Someone or something is using the animals at the top of the food chain as hit men. How? He teams up with his next door neighbor, Angela, and soon they realize many innocents have been marked for death, and they must find each of them and warn them before they too fall victim to the savagery of nature. While trying to get to the source of the animal assaults, Ramsey finds himself running down leads all over central Florida and southern Georgia. He is ambushed by his old enemies, the Whitaker brothers, and one night he finds himself in a fight for his life against an unknown assailant. Someone is out to stop him, but the former Army Ranger and Orlando cop has never been stopped at doing anything and is not about to let it happen now.
