The Doctor and Romana land in Budapest, intent on enjoying another holiday, but shortly after landing they find themselves too late to save the life of a man who has seemingly been attacked by a vampire. As they learn that this is the latest in a series of violent attacks, it becomes clear that they have stumbled onto something that needs investigating.
Aided by a vampire hunter who is searching for Dracula, they look into the nearby Buda caves, currently being used for storage by the military - and find that the soldiers have problems of their own.
Stalked through the tunnels by a monster, and up against an ancient evil, the race is on to escape alive - and foil the dastardly schemes of the maniacal Zoltan Frid.
