Miriam Blaylock is a vampire, promising specially chosen humans Immortality as her vampire lovers. As the film begins, her companion is John, a talented cellist whom she married in 18th century France. In a night club in New York, they connect with a young couple who they bring home and feed upon by slashing their throats with a bladed Ankh pendant. The bodies are disposed of by an incinerator in the basement of John and Miriam's elegant New York townhouse, where they pose as a wealthy couple who teach classical music.
