Haematologist Peter Van Bloed is brought to Transylvania by Countess Dracula who offers him a million dollars if he can come up with an artificial blood substitute. The Countess explains that her longevity is due to bathing in the blood of virgins. Her two twin sons Vladimir and Ladislas obtain virgins by abducting women from the clothing store they run. Van Bloed requires a large supply of virgins for his experiments. When the policewoman Nancy comes investigating the disappearances, the Countess has her imprisoned. After encountering Nancy, Van Bloed falls in love with her.
