In an East European village, a young altar boy discovers the corpse of a young woman crammed inside a church bell, another victim of Dracula [Christopher Lee]. One year later, in 1896, following the events of the previous film, Dracula has been destroyed. Monsignor Ernst Mueller [Rupert Davies] arrives on a routine visit, only to find the altar boy is now a frightened mute and the Village Priest [Ewan Hooper] has lost his faith. The villagers refuse to attend Mass as the shadow of Dracula's castle touches the church. To end the villagers' fears, Mueller climbs to the castle to exorcise it.
The terrified Village Priest follows only partway up the mountain, and Mueller continues alone. As he exorcises the castle, attaching a large metal cross to its gate, a thunderstorm erupts. The priest stumbles and is knocked unconscious when his head strikes a rock. The blood from the head wound trickles into a frozen stream through a crack in the ice and onto the lips of Dracula, reviving him. Mueller returns to the village, reassures the villagers, and then returns to his home city of Keinenberg, where he lives with his widowed sister-in-law, Anna Mueller [Marion Mathie].
Unknown to Mueller, Dracula takes control of the priest. Furious that his castle is now barred to him, Dracula forces the enslaved priest to reveal the name of the exorcist. The priest desecrates a coffin to provide a sleeping place for Dracula and leads him to Keinenberg, where the Count determines to take his revenge on Mueller's beautiful niece, Maria [Veronica Carlson]. Dracula enslaves a tavern girl named Zena [Barbara Ewing]. Zena almost succeeds in bringing Maria under Dracula's power, but Maria's boyfriend Paul [Barry Andrews], who lives and works in the bakery beneath the tavern, rescues her. Dracula kills Zena and orders the priest to destroy her corpse before she turns into a vampire, so the priest burns her body in the bakery ovens. The priest then helps Dracula locate Maria. Dracula climbs over the rooftops of nearby buildings, enters Maria's room, and bites her.
Mueller enters Maria's room just before Dracula has bitten the girl again and pursues a fleeing figure across the rooftops. He is knocked down by the priest. Mueller makes his way back home, where his sister-in-law cares for him. He summons Paul, knowing that he will help protect Maria because of his love for her. Mueller passes on a book, which contains the rites of protection against vampires and ways to defeat them, before he succumbs to his wounds. Paul enlists the priest, not knowing he is under Dracula's spell. Unable to break free from Dracula's influence, the priest attacks Paul as they watch over Maria, who is falling under Dracula's spell. Paul defeats the priest and forces him to lead the way to Dracula's lair. They try to stake Dracula through the heart, but the faithless priest and the atheist Paul are not able to say the required prayer, so Dracula rises and removes the stake himself. He kidnaps Maria and flees to the castle, pursued by Paul and the priest.
At the castle, Dracula orders Maria to remove the cross from the door. She throws it over the parapet into the ravine below, where it lands upright, wedged between the rocks. Paul fights Dracula on the parapet and throws him over the side, and he is impaled on the cross. The priest, freed from the vampire's influence, recites the Lord's Prayer in Latin before collapsing and Dracula perishes, dissolving into dust. Reunited with Maria and having apparently regained his Christian faith, Paul crosses himself while viewing Dracula's remains.
