Denise "Birdie" Beardtom of the Alaska State Troopers has barely recovered from a case that almost cost her life. A woman used to saving victims almost became one herself, which is why she's still jumpy when another woman ends up dead under her jurisdiction. The woman was raped and murdered, and there are no clues to lead them to a possible suspect. Birdie enlists the help of her usual team: Trooper Miles, Trooper Masonic, and Lieutenant Steven Lambert, known as "The Loo." Together, they scour rivers and forests for any evidence of a killer who seems to have no conscience. The body count quickly rises, so the FBI sends an agent to help in the search. Despite all the expertise, Birdie finds herself no closer to finding their killer. The Loo does his duty and heads as far away as New York City, where he uncovers startling information about the serial monster that eludes them. Again, Birdie somehow feels personally connected. She can't shake the feeling that the killer is coming for her. She and her team have to stop him before her life becomes the next he takes.
