They find themselves in a terrifying castle, the guest of Anatol (Carl Lange). He brings Count Regula back to life. The Count reveals that Roger is the last member of his executioner's family and Roger must die to complete his revenge. Lillian will be the thirteenth maiden to die by his hand, this will enable him to complete his twisted experiments and create an elixir of eternal life...
Not the most original of horror films, it seems to take many elements of well-known horror tropes, including a pendulum pit and iron maidens and mixes everything up in a fairly psychedelic and very grotesque romp. Christopher Lee gives a great turn as the evil count (but of course you would expect nothing less!)
