In a distant galaxy, the planet Tranculon, known for its red water, faces severe droughts due to its two suns, leaving few survivors, including Transpirella. After discovering humans as a food source during a 1960s Earth astronaut crash on her planet, Transpirella arrives on Earth, seeking sustenance but grows fond of humans, viewing them as friends and lovers. However, her fellow Tranculonian, Dracula, has sinister plans to dominate humanity, turning them into a vampire army under Satan's guidance to dominate Earth and beyond. Transpirella, a vampire with superhuman strength from her dual-sun planet, teams up with renowned vampire hunter Dr. Van Helsing, his trans offspring Eve, and Transpirella's sidekick, magician Femdragon, to stop Dracula's evil scheme.
