He had it planned out to perfection. She was weak and pathetic, past the point of fighting for her life. She must know she couldn't win, and soon it would all be over...on the count of three.
A woman is reported missing in Miami, Florida, and Detective Kelly Marsh starts the investigation into her disappearance. But Marsh soon recognizes notable similarities between this woman's history and that of two victims, brutally murdered, their cases still unsolved. Marsh's gut tells her the killer may be back, and she'll need assistance from the FBI to take down this monster. Special Agent Brandon Fisher and his team with the Behavioral Analysis Unit jet south to coordinate their efforts with the local detective.
With evidence mounting that the missing woman's fate is looking much the same as the other victims, Brandon and the others must work at their highest level of efficiency and cunning if they're going to stand a chance of saving her. After all, as they quickly come to realize, they're hunting a killer with an insatiable appetite for blood. And if the FBI team isn't careful, one of them may not make it out of Miami alive.
