When a spaceship from Earth crash lands on the dying planet Drakulon, the remaining dying inhabitants, the Vampiri, sends Vampirella to investigate to find the pilots from Earth have blood flowing through their veins; blood which at one point in time flowed in rivers through Drakulon but now has stopped flowing, causing the inhabitants to die off. Vampirella is able to pilot the spaceship back to Earth where she becomes a "good" vampire, and devotes her energy to ridding our world of the evil vampires.
