After killing her former mentor-turned-vampire, U.S. Marshal Jameson Arkeley, Caxton was nearly left for dead. Taken to prison for assaulting a convict, she now faces her most harrowing hours yet. Locked up in a Pennsylvania correctional facility that holds the state's death-row inmates, not to mention countless murderers and drug dealers whom Caxton herself has put away, she is an easy target.
But it gets worse. The oldest living vampire, Justinia Malvern is still on the loose and manages to infiltrate the prison. There she uses the inmates as livestock – taking daily donations of blood at will and slaughtering any who don't cooperate. But it's Caxton's blood she's most hungry for, and when Caxton's girlfriend, Clara, comes to visit but ends up trapped there, Justinia will use her as a pawn to get to her most sought-after prey...
