She's the only one who can catch the killer, who's left a trail of bodies in a rural community outside of Las Vegas.
But the more Jessica finds out, the less clear her case becomes. Out of options, she's forced to consult her serial killer ex-husband-to gain additional insight into the crimes and the killer's motivations.
By the time Jessica realizes that pursuing this case is a deadly mistake, it's too late to turn back. Can she catch the killer, or will she be the final addition to a killer's masterpiece?
