On July 17, convicted serial killer Ronald Jeffreys was executed for three heinous murders. He went to his grave with a terrible truth no one would listen to.
Three months later, another body is found - killed in the same style as Jeffreys' victims. Is there a copycat killer on the loose? Or is this the real thing?
Sheriff Nick Morrelli isn't equipped to deal with this case that is terrorising the small, close-knit community of Platte City, Nebraska. Knowing he needs help, he calls in one of the FBI's best criminal profilers, Maggie O'Dell. And with the help of a small-town sheriff who is clearly out of his depths, Maggie starts to put together the gruesome picture of a killer. The picture of someone who has already been executed for his crimes.
When another victim is found and a third kidnapped, Nick and Maggie realise they're running out of time. And the terrible truth begins to become clear. Was Jeffreys convicted of crimes he didn't commit? Or has a cold-blooded killer been given the chance to perfect this crime?
