Ancient vampires live under the city, thirsting for new blood, creeping out through the ductwork. They escape tunnels to prey on the unsuspecting. On her way home from working at the theater, Deirdre meets Benton, but he is a reluctant vampire, longing for release from a curse he fears will last for eternity. Deirdre is attracted to Benton, who hides his vampire nature to show her his human side. As she finds herself falling in love with him, his identity is revealed and she prays for help to find a way out of the blood curse. One day after church, she confides in the priest, Father More, who has a taste for horror literature and considerable knowledge of vampire lore. He cautions her against forming a relationship with a vampire, but he tells her he will investigate ways to break the curse. Sidell, on the other hand, relishes his life as a vampire, and uses his glamour to ensnare one of Deirdre's friends. Can Deirdre slay a vampire to save an innocent person? Will Father More be able to free Benton? Will Deirdre accept her destiny as a slayer?
