TWC returns to their home state to investigate Brushy Mountain State Penitentiary, which held some of the most violent criminals in Tennessee, including it most infamous inmate, James Earl Ray, who assassinated Martin Luther King. In the order to trap the former inmate of a little person named Jack Jett who was stabbed 19 times, the guys build a "Wraith Fog Trap" with four spinning lasers that projects onto a moisture-rich thick fog to draw entities in, transforming into electricity with a Jacob's ladder.
