When a body is found, FBI agent Mike Atkins teams up with his new partner Chelsea Turner to unravel the clues. Confusion mounts when it seems the victim was murdered by two different methods. Was there one killer or two? Mike and Chelsea are no closer to solving the murder when the killer or killers strike again. Will they figure it out before more people die or will they too become victims?

A trail of blood and half a handcuff is the only clue . . . People are vanishing. Never to be seen or heard from again. Mike and Chelsea team up again to stop the threat but this time the killer wants Chelsea. He won't stop until he can cuff and torture her, saw her to pieces, and throw her dismembered body into his collection of kills. Will Chelsea be able to survive this cold-blooded killer? Or will she also become one of the missing?
