This clever spin off of The House of Frankenstein finds the Baron, Baroness and their repulsive retainers, Igor and Frau Lurker, going to stay at a macabre Transylvania fortress. Excitement turns to terror when they are greeted by more than a few of their mortal (and immortal) enemies. They are to take part in an unholy survival test involving ghouls, ghosts and the fiendish Dr. Jekyll. The Frankensteins flee from cellar to attic, desperate to escape a fate worse than death!
