In 1897, in a castle near the town of Werewolfville in the Carpithians, a slightly deranged Professor Orfanik experiments with his new inventions which include, even at this early date, television and a film camera. He is also an obsessed opera fan, keeps the body of his favorite diva preserved in a crypt in the castle. In order to keep away nosy visitors, the baron's mad-scientist assistant, invents all sorts of spooky phenomena in order to give the castle a creepy reputation.
