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 terrorizing 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 realize 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-blodded killer been given the chance to perfect his crime?
