That evening, Tundra appears outside her window and attempts to hypnotize her, but is interrupted by George and Diana’s father, Professor Orloff.

Santo deduces that since vampires cannot survive in sunlight, they must have a lair, but the professor has been unable to decode that information from the prophecy.

The inspector comes up with a plan to send Diana out as bait, so they can follow the vampires to their lair and Santo can destroy them.

Santo escapes and defeats the remaining henchmen, sets fire to the vampire women in their coffins, and frees Diana.
