Linda Westinghouse, a young American lawyer working for a law firm in Istanbul, has been having erotic dreams about a beautiful young woman every night. At a nightclub with her boyfriend Omar, Linda sees the mysterious woman from her dreams for the first time performing an exotic dance. The next day, Linda tells her psychiatrist, Dr. Steiner, that these dreams evoke both fear and arousal in her; he concludes that she is sexually frustrated and advises her to find herself a more satisfying lover. Linda is sent to the remote peninsula of
Anatolia, where she is set to travel to the Kadidados Islands to handle the inheritance of Countess Nadine Carody. At Linda's stopover, the hotel porter, Memmet, warns her not to go to the island, claiming it is "a place of insanity and death". Linda follows Memmet to the wine cellar, but flees after catching him torturing a young woman. Linda arrives at Nadine's beach house, realizing she is the woman from her dreams. Nadine explains that she has inherited the estate of
Count Dracula. When Linda begins to feel dizzy after drinking red wine, Nadine takes her to a room where the two have sex, and Nadine draws blood from Linda's neck. Linda later awakens to find Nadine motionless in a swimming pool and faints. The next day, Linda awakens at Dr. Alwin Seward's private clinic with no memory of her encounter with Nadine. Meanwhile, one of Dr. Seward's patients, Agra, is having a psychotic episode, claiming to have visions of Nadine. At Nadine's mansion in Istanbul, she recounts to her manservant Morpho that centuries earlier, she was attacked and raped by soldiers in her native Hungary, before she was rescued and then vampirized by Count Dracula, leading her to hate men. She also expresses her desire to turn Linda into a vampire. Nadine uses her powers to compel Linda to go to her mansion, where the two drink blood and have sex. Back at the clinic, Dr. Seward informs Linda that to break free from a vampire's curse, she must split the vampire's head with an axe or pierce it with a pole. Memmet kidnaps Linda. When Nadine arrives at the clinic looking for Linda, she meets Dr. Seward, who admits that he had been waiting for Nadine's arrival so she can turn him into a vampire. Nadine refuses and has Morpho kill him. She then visits Agra's room and bids her goodbye. While Omar enlists Dr. Steiner's help in locating Linda, Memmet holds her captive and reveals that his wife, Agra, became insane after meeting Nadine on the island. Linda kills Memmet and escapes. Omar and Dr. Steiner go to Nadine's mansion, but she and Morpho have returned to her beach house in Anatolia. Linda runs back to the beach house and finds Nadine lying in bed, dying. Nadine begs Linda for some blood, but Linda, determined to break free from Nadine's curse, bites her neck and stabs her through the eye with a pole. Distraught over Nadine's death, Morpho kills himself. Linda is found by Omar and Dr. Steiner, and Omar tries to convince her that everything she experienced was a dream, but Linda knows this is not the case. == Cast ==
