The series follows four vampire roommates living together in Staten Island: Nandor the Relentless, the self-appointed leader of the house; Laszlo and Nadja, a married couple; and Colin Robinson, an energy vampire who works in an office and drains humans of their energy by boring or irritating them. The other vampires are often annoyed by his presence. They are joined by their familiars, including Guillermo, who has served Nandor for ten years and hopes to become a vampire one day.
