A woman's charred body has been found inside a burned car atop a hill in Knoxville. Was this an accidental death, or murder? Forensic anthropologist Bill Brockton is on the case, torching bodies to research how fire consumes flesh and bone. Days later, he receives a mysterious package - a set of cremated remains that seems entirely unreal. As Dr Brockton investigates, he uncovers a truth too horrifying to believe… Little does Dr Brockton know that his research is about to collide with reality. Disgraced medical examiner, and Dr Brockton’s nemesis, Garland Hamilton, has escaped from custody on the way to his trial. So begins a deadly game of cat and mouse with Dr Brockton’s life at stake. Finally running Hamilton to ground, Brockton finds only the incinerated remains of his enemy, or does he? The answer, along with the renowned anthropologist’s ultimate test, comes in a searing moment of truth.
