Plot
In 18th-century Eastern Europe, French Marquis Jacques Saturnin du Antoine loses his horse and companions through being robbed. A stranger advises him to go to the house of a man named Gorcha. Jacques Antoine eventually reaches Gorcha's house where the latter's family resides.
Gorcha's elder son, Jegor, soon arrives home, having spent the past month seeking revenge against the Turks who pillaged the village. Gorcha left to fight the Turks, and had said that if he did not return within six days, it would be because he had died fighting; if he should return after those six days, he would have become a vourdalak and nobody should let him in. Jegor, however, does not believe in vourdalaks. He knows where a horse for Jacques Antoine can be found, but it would have to wait until the next day.
Jacques Antoine eventually approaches Gorcha's daughter Sdenka and aggressively tries to seduce her. In turn, she tricks him into almost falling off a cliff. Sdenka had a lover, and because everyone in the area knows, she now cannot get married. She was planning to flee with her lover, but someone found out and killed him.
That evening, six days since Gorcha left, he is spotted lying at the edge of the forest, looking like a corpse. The dog of Gorcha's youngest son, Piotr, will not stop barking at the old man. Jegor compels Piotr to shoot it. Gorcha reveals that he murdered the band of Turks' leader, whom Jegor failed to kill.
That night, Jacques Antoine has nightmares about Gorcha. The following day, Gorcha is missing and Jegor's son Vlad is unwell.
That night, Jacques Antoine sees Vlad walking outside. He appears to be sleepwalking, and Gorcha is nearby, chewing on his shroud. Jacques Antoine attempts to subdue Gorcha, who hurls him against a tree before drinking Vlad's blood. Jacques Antoine awakens the next morning and finds the family digging a grave for Vlad's dead body.
During the funeral, Piotr and Sdenka encourage Jegor to drive the stake through Vlad's heart. However, Gorcha interrupts him, reproaching the family for Vlad's death. Piotr attempts to attack Gorcha with the stake, but loses his nerve. Gorcha implies to Sdenka that it was he himself who was responsible for shooting her lover.
Gorcha compels Jacques Antoine and Sdenka to dance for him. Piotr, whose supposed effeminacy was criticised by Jegor and Gorcha, appears wearing lipstick and flowers, wanting to kill his father, who shoots him dead. Blaming Jacques Antoine for the family's recent misfortunes, Jegor beats him. He announces that Jacques Antoine will be given a horse the next morning and must leave to never return; if he comes back, Jegor will kill him.
Jegor leaves Jacques Antoine bound in the cellar for the night, and he is woken by Vlad calling for his mother, Anja. Outside, Vlad approaches Anja; Jacques Antoine tries to warn her to stay away, to no avail. Mother and son embrace, and he drinks her blood. In the morning, Sdenka approaches Jacques Antoine, declaring that she will throw herself from the cliff, as Piotr was the only thing keeping her alive. She then leaves.
Jegor and Anja, now a vourdalak, give Jacques Antoine a horse. In the woods, however, he cannot find Sdenka. Returning to the house that evening, Jacques Antoine believes that he sees her singing in a bedroom. He tries to convince her to leave, but instead she seduces him, and they start having sex. However, Jacques Antoine discovers that he is actually interacting with Gorcha, who has been drinking his blood. Jacques Antoine stakes Gorcha and stumbles into the dining room, where Jegor and his vampirized brother, wife and son are seated around a table. Jacques Antoine sets the house on fire and rides away.
At dawn, he finds Sdenka at the edge of the cliff and convinces her not to jump, informing her that she is free. Having been bitten, Jacques Antoine gives her his horse and a map of Europe before jumping off the cliff. Sdenka rides away, chewing a shroud. A French duchess later takes her in.
