A string of gruesome deaths in the Shiprock area has attracted the attention of FBI agent Diane Lopez. The killer is unmistakably a vampire—but the only vampire Diane knows of is State Police officer Lee Nez. One of the good guys. The victims worked for a secret government lab that was studying a captured vampire, Stewart Tanner. Driven mad, Tanner broke free and took revenge on his tormenters. Now he's threatening to kill a powerful judge unless the feds promise to leave him alone. Forced to use his supernatural abilities to track a vampire gone bad, Lee has trouble concealing his true nature from Dr. Victor Wayne, the researcher who captured Tanner in the first place. Lee knows that he has to find Tanner before the rogue vampire kills again. He also knows that there can be only one outcome when they meet. Either he, or Tanner, will die.
