Count Dracula (Christopher Lee) has developed a deadly strain of bubonic plague. He plans to use his Satan-worshipping disciples to release the plague in London in an effort to destroy the human race. Standing in the way is Dr. Van Helsing (Peter Cushing), Dracula's nemesis, who must not only stop his archenemy but also save mankind. This was the last Hammer horror film featuring Christopher Lee as Dracula.
