Philadelphia homicide detectives Kevin Byrne and Jessica Balzano's first assignment from the Cold Case files is the brutal murder of a young runaway. The lifeless body of Caitlin O'Riordan was found carefully posed in a glass display case in the desolate Philadelphia Badlands but, as Byrne and Balzano rapidly discover, she was just the first pawn in the killer's twisted game ...

A mysterious phone call leads them on a scavenger hunt for a second victim. This time a young girl has been dismembered, her body parts left in three boxes in the basement of a deserted house. More clues lead to other victims and, as the body count rises, it becomes clear that there is a serial killer on the loose, hell-bent on completing the 'performance' of a lifetime.
