The film is set deep in the heart of Transylvania and the story appears to take place sometime during the mid19th century. Professor Abronsius, formerly of the University of Konigsberg and his apprentice Alfred are on the hunt for vampires. Abronsius is old and withering and barely able to survive the cold ride through the wintry forests, while Alfred is bumbling and introverted. The two hunters come to a small village seemingly at the end of a long search for signs of vampires. The two stay at a local inn full of angstridden townspeople who perform strange rituals to fend off an unseen evil. While staying at the inn, Alfred develops a fondness for Sarah, the overprotected daughter of the tavern keeper Yoine Shagal. Alfred witnesses Sarah being kidnapped by the local vampire lord Count von Krolock. Crazed with grief and armed only with a bunch of garlic, Shagal attempts to rescue her but doesnt get very far before hes captured, drained of his blood and vampirised. After Shagal rises and attacks Magda, the taverns beautiful maidservant and the object of his lust while he was still human, Abronsius and Alfred follow his trail in the snow, which leads them to Krolocks ominous castle in the snowblanketed hills nearby. They break into the castle but are trapped by the Counts hunchback servant, Koukol. They are taken to see the count, who affects an air of aristocratic dignity while questioning Abronsius about why he has come to the castle. They also encounter the Counts son, the foppish and homosexual Herbert. Meanwhile, Shagal, no longer caring about his daughters fate, sets up his plan to turn Magda into his vampire bride. Despite misgivings, Abronsius and Alfred accept the Counts invitation to stay in his ramshackle Gothic castle, where Alfred spends the night fitfully. The next morning, Abronsius plans to find the castle crypt and destroy the Count by staking him in the heart, seemingly forgetting about the fate of Sarah. The crypt is guarded by the hunchback, so after some wandering they attempt to climb in through a roof window. However, Abronsius gets stuck in the aperture, and it falls to Alfred to complete the task of killing the Count in his slumber. At the last moment his nerve fails him and he cannot accomplish the deed. Alfred then has to go back outside to free Abronsius, but on the way he comes upon Sarah having a bath in her room. She seems oblivious to her danger when he pleads for her to come away with him, and informs him that a ball is to take place this very night. After briefly taking his eyes off her, Alfred turns to find Sarah has vanished into thin air. After freeing Abronsius, who is half frozen, they reenter the castle. Alfred again seeks Sarah but meets Herbert instead, who first attempts to seduce him, and then, after Alfred realizes that Herberts reflection does not show up in the mirror, reveals his vampire nature and attempts to bite him. Abronsius and Alfred flee from Herbert through a dark stairway to safety, only to be trapped behind a locked door in a turret. As night is falling, they become horrified witnesses as the graves below open up to reveal a huge number of vampires at the castle, who hibernate and meet once a year only to feast upon any captives the Count has provided for them. The Count appears, mocking them and tells them their fate is sealed. He leaves them to attend the ball, where Sarah will be presented as the next vampire victim. The hunters escape by firing a cannon at the door  substituting steam pressure for gunpowder  and come to the ball in disguise, where, although exposed by their reflections in a huge mirror, they are able to grab Sarah and escape. Fleeing in a horsedrawn sleigh, Abronsius and Alfred are unaware that it is now too late for Sarah, who awakens in midflight as a vampire and bites Alfred, thus allowing vampires to be released into the world.
