Imprisoned at Alcatraz for over forty years, Dr. Laura Olson dreamed of two things: freedom and meeting back up with the man who spared her life and gave her a chance to serve her country from behind bars. All that changes when a shapeshifter comes to the Rock, ripping out and eating the hearts of the inmates to steal their memories and paranormal abilities. The shapeshifter sweeps through the prison and finally attacks Dr. Olson, stealing her heart and her undead powers before fleeing the country. When the shapeshifter declares himself to be the second coming of the Mayan blood god Kukulcan to the people of the Yucatan, America's anti-supernatural forces spring into action, recruiting Dr. Olson and giving her a chance for payback. The vampire now must work with a team of living stone soldiers, a teenager who can freeze objects with her mind and the super soldier who captured her long ago. Can the undead Doctor keep her new team alive long enough to get revenge, or will she succumb to her blood thirst and join with the new Kukulcan?
