"It seems that venerable Dr. Frankenstein (Karloff) has decided to hang up his mad-scientist frock after reaching the pinnacle of his profession: a potion that causes "complete destruction" in a suspiciously nuclear cloud of smoke. Hoping to choose a successor among his Universal Classics brethren, Dr. Frankenstein invites Dracula, the Wolfman, the Hunchback of Notre Dame, the Mummy, the Invisible Man, Dr. Jekyll, the Creature from the Black Lagoon, and his own stable of Igor, Frankenstein's Monster, and some red-headed bombshell [Francesca-above] who does a nice tango with Drac, to Evil Island and the eponymous party."
