Four travelers unwittingly revive the bloodsucking count.

Charles and Diana Kent, Charles's brother (Alan), and Alan's wife (Helen) vacation in the Carpathian Mountains, but they are told to stay out of the Carlsbad area, where the inhabitants are still frightened of vampires even though Dracula has been dead for 10 years. These people ignore the advice and hire a coach to take them through the area. As the coach passes Dracula's castle, however, the driver leaves them standing on the road, and he turns back. A driverless coach then takes them on to the castle, where they are persuaded by Klove, the butler, to spend the night. Later, Alan is hacked to death by Klove, and his blood drips over Dracula's ashes and causes the vampire's revivification. Dracula quickly attacks Helen and transforms her into a vampire. Charles and Diana use the protection of the cross to escape from the castle to a monastery run by sympathetic Father Shandor, one of Dracula's archenemies. Ludwig, an old man, invites Dracula and Helen to enter the monastery, and Helen tries to attack Charles but is killed when a stake is driven through her heart. Charles nearly kills Dracula, but night falls rapidly, and Dracula fights off the attacker and then retires to his coffin on the ice-covered moat. Father Shandor, recalling that vampires can be killed by running water, breaks up the ice and allows the water to flow over Dracula.
