Dispatched to a possible kidnapping site, Carlisle Homicide Detective Erin McCoy, her K-9 Officer Shadow, and other K-9 units are beating the bushes behind the warehouse where the star of the Frank W. Woolworth documentary film crew was last seen. The dogs soon locate a body dressed in period costume lashed and nailed to a tree. Extracting the nail, Mac sees fresh blood. Quickly, the men free him and laid him down. Shadow jumps on his chest. The mystery begins when he opens his eyes.

Tension mounts as the detectives dig into the murky business of murder-into the depths of the actors, cast, crew, and childhood of the suspects until they reveal the evil hearts of the killers.
