Serial killers, they walk among us. Killers with no conscience, remorse, and some say, no soul. Most kill at will and with no set pattern to track and capture. Reports say at any given time a dozen such creatures are wandering around the country, taking their victims at will. We all know someone who disappeared, never to be found. Some are adults, some are children — and the evil is out there, waiting. Stalking.

FBI Special Agents Ben Hawk and Connie Sanchez hunt these serial killers. They're the best in the Bureau and everyone knows it, including the killers. Their unique camaraderie, banter and practical jokes help them to mentally and emotionally handle the severe pressure they experience.

Young women are disappearing from Wisconsin Universities, their bodies grotesquely posed along the banks of the Wolf River. Ben and Connie are called in by the state's governor to end the killing spree and bring down the killer, by the book. Off the record — by any means necessary, even if outside the law.

The team discovers Connie is now in the killer's sites. Their urgency increases to kill this murderer before he can kill again. And Connie is determined she won't be the one to die.
