On a remote island, the beautiful vampire Countess Nadine Carody (Soledad Miranda) lures unwary victims with her seductive nightclub act and sets her sights on Linda (Ewa Strömberg). Linda begins dreaming about Nadine and seeks her home on an island. She is interrupted by Memmet (Jesus Franco) who warns her not to go to the island. Linda follows Memmet to his chamber where she walks in on him torturing a young woman. She escapes this encounter and proceeds to the island where Linda meets Nadine. The two go swimming and Nadine notes that the home they are staying at used to belong to Dracula. After Linda begins to feel dizzy from drinking wine, Nadine takes her to a room where the two have sex and Nadine draws blood from Linda's neck. Linda later finds Nadine motionless in a swimming pool and faints.
