Five beautiful showgirls are trapped by a storm and find refuge in a creepy old castle. The owner of the castle, a strange nobleman, has a secret laboratory in the basement and has his own plans for the girls.
Lucas [Alfredo Rizzo], manager of five showgirls -- Vera [Lyla Rocco] , Katia [Maria Giovannini], Erika [Erika Dicenta], Ilona, and Magda -- has just skipped out on their hotel bill and is trying to reach thenext town in their bus when they learn that the road has been blocked by alandslide. Since they can't turn back, they take the only other road,which leads to the Castle of Kernassy, a place where no local would dareto go. Lucas could care less about local superstitions. Thinking about thepossibility of free digs, he heads for the castle. When they arrive at thegate, Vera senses a strange feeling of familiarity, but the caretakerstell them to move on, until Count Gabor Kernassy [Walter Brandi] sets eyes on Vera.Suddenly, he agrees to put them up for the night. There is a condition,however. No one is to leave their bedrooms at night, regardless of whatthey might hear.
As a storm rages, Vera notices the Count looking at her through thewindow. She confronts him, but he only wants to talk about her background.Where does she come from? Vera provides little details due to the factthat her parents died when she was young. Later, Katia comes to Vera'sroom because she can't sleep and then decides to take a shower. Because itis rather cold, Katia slips into Vera's coat. Before showering, however,Katia goes exploring after hearing a kitten meowing. She follows it to atower room.
The next morning, Katia is found dead on the ground at the foot ofthe tower. It appears that she has fallen. Unfortunately, the river hasrisen, and the visitors are forced to stay longer at the castle, eventhough they now want to leave. Later, after Katia is buried and while thegirls rehearse their dances, Vera returns to her room to rest. Whilewalking through the corridor, she notices a painting of MargheritaKernassy, who looks remarkably like Vera herself. When Vera asks the Countto tell her about Margherita, he explains that she was an ancestor of hiswho died in the 1780s. Because he thinks Vera might be a reincarnation ofMargherita, he warns her to leave the castle as quickly as possible. Veraadmits that she feels at home in the castle and safe with the Count. Theyfly into each others' arms.
Later that evening, as Vera is getting undressed for bed, she noticesthe shadow of a man slinking along her wall. She tosses on a coat and goeslooking for him in the gardens. When she passes Katia's grave, she ishorrified to find that Katia's body has been dug up and removed. Then shenotices the Count standing in the bushes. When she attempts to speak withhim about Katia's body, he runs off. The housekeeper is of no help either.In fact, she admonishes Vera for being too curious.
The next morning, Vera goes looking for the Count and wanders intowhat looks like a laboratory where she discovers Katia's body. When Veraconfronts him, the Count admits that he dug up Katia's body in order tocontinue his investigation into a "diabolical" force that turns men intoimmortal monsters and gives them an insatiable thirst for human blood. Healso suspects someone murdered Katia, thinking her to be Vera because shewas wearing Vera's coat at the time. But who would want to kill Vera? TheCount warns her again not to leave her room after nightfall, not even ifshe hears his voice calling to her.
That night, a naked Katia baring fangs appears to Lucas, but he goesinto a faint. Vera hears someone outside her bedroom door, calling out thename "Margherita." She throws her coat over her nightgown and goes toinvestigate. With bats squeaking over her head, Vera makes her way downinto the crypt, where she comes upon two coffins...one for MargheritaKernassy and one for Gabor Kernassy. Suddenly, the Count appears, bareshis fangs, and sucks blood from Vera's neck. When Vera regainsconsciousness, it is the next morning. The housekeeper informs her thatshe has had a high fever and been delirious all night. Vera concludes thather encounter with the Count in the crypt must have been a fever dream.But when Vera sees the two holes in her neck, she realizes otherwise.Immediately, she packs her bags and goes looking for her friends.
The first person she meets is the Count. Vera hightails it away fromhim. When the Count gives her chase, Vera opens a door to escape and runsinto...the Count. With Counts on both sides of her now, Vera faints. Thetwo Counts struggle. When the vampire Count knocks out the human Count, he(the vampire Count) carries Vera down into the crypt and places her inMargherita's coffin. Katia is jealous and vows to kill Vera before thevampire Count can make Vera immortal. Not to be deprived of his Margheritaagain, the vampire Count drives a burning stake through Katia's heart.
Meanwhile, the human Count has followed them down into the crypt. Heinforms the vampire Count that the serum is almost ready and that it willput an end to the vampire affliction, but the vampire Count is notinterested. Indeed, he considers vampirism "a significant achievement ofthe intellect and the greatest joy known to mankind." A little morefighting breaks out, the end of which results in the human Count pullingdown the curtains and letting in the sunlight. In his struggle with thelight, the vampire Count impales himself on a poker and fades away. Thehuman Count carries Vera upstairs.
Everyone is happy that the vampire Count is now dead. A short whilelater, Vera and her friends drive off in their bus, leaving the humanCount behind to tie up a few loose ends at the castle, after which he plansto join Vera. [Original Synopsis by bj_kuehl.]
