Plot:
In the dead of night, a terrified Tilda is running through the woods.
Elsewhere, in the Karnstein castle, Laura awakens and knows her cousin, Tilda, has just been killed. Rowena and Annette are unable to calm the distraught Laura.
The next day, Friedrich Klaus arrives to meet the Count Ludwig Karnstein (Christopher Lee). The always sinister looking Count wants Lyuba to examine the genealogical
records of the Karnsteins to find any details about Sarah of Karnstein who was burnt at the stake as a witch for killing girls. The records and documents are to be examined
and if possible to find any pictures of Sarah.
The hot blonde Annette informs the Count about Laura’s nightmare concerning Tilda.
In the library, Lyuba begins his research.
Rowena and Laura plan to visit the crypt tonight. Count Ludwig tells Laura of Friedrich staying for a few days.
At dinner, small talk ensues. Friedrich talks about some of the history. He is told about a nearby village that was destroyed.
From a document, Sarah proclaims vengeance against the sons of Karnstein. Her revenge will ensue and is sworn by the 5 pointed star. The manuscript has a 5 pointed
star cut out of it.
In the crypt, Rowena tries contacting Sarah of Karnstein. She sets the star on fire.
Flashback, a torch carrying mob condemns Sarah of Karnstein who vows to return one day as a Karnstein and avenge herself.
Laura awakens and is speaking as Sarah of Karnstein. At first, Rowena tries passing everything off as just nightmares. When Laura learns she was possessed she
heads for the castle turret. Rowena stops her from jumping by promising to kill her if she becomes evil.
Annette is in Count Ludwig’s bedroom. They talk of Friedrich and the Karnstein prophecy: the number of Karnsteins who have died mysteriously. Ludwig is sure Laura is
connected to it. Annette is sure Friedrich will find proof that Laura doesn’t look like Laura. Well, Ludwig wants to throw a log in Annette’s fireplace. However, she wants to
get married and become a countess with all the money.
A hunchback shows up. He talks with Rowena about how Tilda was killed. She was the third Karnstein since April.
Friedrich starts putting the moves on Laura when a coach throws a wheel close to them. They find a woman whose daughter, Lyuba, is sick. Leaving her behind, the
woman continues traveling.
Lyuba and Laura get along. Really get along…
Friedrich finds Annette snooping through his papers. She claims that Sarah of Karnstein’s face is nearby. Refusing to speak at first, she admits it is Laura.
That night, Laura awakens. She sees Tilda offering her Karnstein blood to drink and claims Laura killed her. Tilda and Laura start nuzzling each other until Laura
sees Tilda has became a skeleton. Screaming bloody murder, Lyuba rushes in to check on her. Laura pleads for her to stay with her.
Friedrich is hard at work restoring documents. He asks Rowena about the paintings in the castle and if Annette has a special relationship with the count. Rowena
storms off.
Friedrich tells the Count that apparently there is one painting of Sarah of Karnstein in the castle that was painted over. Count Ludwig wants him to keep researching
but not to search for the painting.
Laura and Lyuba frolic in the garden, swinging not in the John Anderson way. Fred stops by and puts the moves on Laura who is now happy that Lyuba is with
her. He wants to help her not feel alone…
Elsewhere, Count Ludwig is glad that Lyuba has arrived. She seems to have helped Laura. Well, Annette doesn’t trust the newcomer. She is less than happy with
Laura who she blames for not being able to marry Ludwig.
That night, Laura seemingly sleepwalks to Lyuba’s room. Over the girl’s pale and quivering neck, Laura has the true energy drink.
Awakening in her bed, Laura rushes to Lyuba’s room, crying she killed her. Friedrich and Count Ludwig inspect Lyuba who has 2 small bite marks on her neck and
let her continue sleeping.
Friedrich asks the Count if he is to find if Laura is possessed by Sarah of Karnstein.
Rowena takes Laura back to her bedroom and finds bloody sheets. No nasty gross-out humor at this period.
The next morning, Laura and Lyuba are talking. Laura is acting awfully strange almost staring at her friend’s neck…The hunchback stops by and gives Laura a
charm against evil. He tells how Tilda was killed and drained of all her blood. The distraught Laura runs off.
She throws the talisman away. Friedrich tries to console her. He tells her about the hidden Sarah of Karnstein painting in the castle. Leaving the room, he finds the
talisman which contains a message written by Sarah.
The approaching Lyuba tells Friedrich about how the hunchback scared Laura terribly. He asks her to console Laura. So that’s what it is called then…
That night, the village bell is ringing. Would you be surprised if Laura is disturbed by this? She asks for Lyuba to stay. Lyuba convinces her going to the castle
will make her feel better by facing her fears.
In the desolate and abandoned village, they find the hunchback hanging from the bell rope. His hands have been cut off.
Back at the castle, Rowena has the hunchback hand with candles on the fingertips. She asks Satan to learn the truth. The hand seems to work like a dowsing rod.
Annette spots Rowena and follows her. Rowena asks for the hand to guide to lead her to the killer. Suddenly, she is stabbed.
Annette runs off but is killed, too.
At the funeral, Rowena is in an open coffin. Count Ludwig, Friedrich, and Laura are standing nearby. Suddenly, Rowena sits up and points at Laura. Laura has another
of her hallucinations. Friedrich and Count Ludwig take her to her room. Lyuba offers to stay with her. We see her wipe Laura’s brow with a Karnstein handkerchief.
Count Ludwig decides to take Laura away in the morning. Friedrich realizes the painting over Ludwig’s desk is gone. He admits that Laura and Annette knew about
the painting.
Lyuba decides to take Laura away. Laura hallucinates about Rowena vowing to kill her. Coming out of it, Lyuba and Laura embrace.
Friedrich mentions the black stone that marked Sarah’s grave. He discovers a secret passage with the missing painting. Restoring the original painting they learn
who Sarah of Karnstein is. However, we don’t see.
Laura and Lyuba run away into the night.
Friedrich and Count Ludwig can’t find Laura and head for the village.
Lyuba leads Laura on.
Friedrich and the Count find a black magic altar. They find a gate and will brave the curse they must endure for crossing it. Plumbing the catacombs, they find a
coffin in the middle of a room. Friedrich is unaware of the rising coffin lid when a zombie grabs him. Ludwig rushes to Friedrich’s side.
Lyuba and Laura are still in the night.
Zombie vows to kill the men. Ludwig recognizes the man as his cousin, Franz, whose daughter Tilda was killed at the beginning of the movie. Ludwig knows
who the killer is.
Ludwig, Friedrich, and Franz break the sealed chamber that holds Sarah’s body.
Lyuba and Laura are still running somewhere…
The shocking secret is revealed. Sarah of Karnstein is Lyuba.
Laura is immediately terrified of Lyuba.
Franz is about to stake Sarah but stopped. Friedrich does the deed instead.
Lyuba collapses and vanishes.
At the castle, in the morning, Count Ludwig, Laura, and Friedrich ride off.
