Before slaying and scalping his victim (always a young woman) a spooky serial killer e-mails his intentions to tabloid reporter David Laney. With Laney's help, the OSC lays a trap, and D.C. Rivers witnesses an abduction in progress. Trailing the killer to an abandoned shack, Rivers is joined by Creegan who confronts the psychopath, poised to slit the throat of his next victim.

Though serial killer Emerson is behind bars, his murder spree somehow continues. Is it a copycat killer or an accomplice? Creegan, Taylor, and Rivers must turn to Emerson himself for help, and he names a trivial but bone-chilling price. Unwittingly, Taylor's new love affair with reporter David Laney is lining her up as the next victim.

Lovingly washed, white-shrouded corpses are turning up across Europe, each with a neat hole in the skull. When the homicides hit Britain, the OSC gets the case, and learns the victims all knew each other in Bosnia, where they worked for a relief agency. He also catches a glimpse of the probable killer captured on a security camera. A man everyone thought was dead.

Serial killer Jim Keller has given police the slip and is widening his scope of victims to include anyone who gets in his way. Eager to prove himself after past mistakes, Rivers throws himself into the investigation and into the killer's line of fire.

Annie Jordan kidnaps the child she says was coerced from her in a baby-brokering scheme. Suspecting links to an international pedophile ring, Taylor and Rivers pose as a childless couple in a sting to nab the ringleaders. Meanwhile, Creegan is becoming smitten with Annie.

While tracking an international pedophile ring, Creegan finds his own children targeted in a revenge attack by a distraught father who blames Creegan for his daughter's death. Meanwhile, Taylor goes undercover to a kid-for-sale orphanage in Albania, risking her job when she returns with a little girl. As the drama reaches its climax, Creegan's affair with Annie Jordan comes to a tragic end.
