Special Agent Katie Freeman and her partner, Michael Powell, step in to assist the local authorities after the discovery of thirteen bodies buried in a small park. The chilling pose of each body and the gruesome manner in which they died indicate a particularly sadistic killer. As Katie and Michael begin investigating the case, they encounter more questions than answers - are these hate crimes or crimes of passion? How did so many men go missing without someone noticing? How are all these victims connected? With more bodies than they can handle and time running out, can they catch the killer before another victim disappears, or will they lose one of their own in the process?

While Katie navigates this case, guilt over the secrets she is hiding from her partner threaten to overwhelm her focus. Can their partnership - and her career - survive if the truth comes out?
