Pat learns that one of Nashville's celebrities, former Tennessee Titan quarterback and public hero Steve McNair, has been found dead in his condo. The body of a young female was also present in an apparent double homicide. With a high-profile case on its hands there is only one detective the Chief of Police wants on the case, and that is Det. Pat Postiglione.

Police found the body of the victim just past what the truckers call "Party Row," and quickly identify her by the bracelet with her name on it: Sara Hulbert.

That's when Pat recognizes an unlikely pattern, leading to a race against the clock to apprehend an active killer before he murders again.
