Investigating the apparent suicide of a colleague's niece, Iowa Deputy Sheriff Carl Houseman uncovers a group that has transformed the dark fantasies of vampire legend into grisly reality: they ritualistically drink small amounts of one another's blood. As Houseman and his partner, Hester Gorse, are drawn deeper into this alternate, alien world, they come to the chilling conclusion that the dead young woman may have been the victim of a twenty-first-century Dracula. Their prime suspect, Dan Peal, is a sinister and commanding presence within the group, but without proof to substantiate such a heinous theory, the trail is in danger of running cold. When their suspicions are bolstered by the report of a card-carrying vampire-hunter who is also pursuing Peal, Houseman and Gorse suddenly find themselves scrambling to track the vampire before he kills again.
