Oh boy, who dreamed this one up? Sadly, this monstrosity is par for the course for 1950s science fiction films, though most are not as bad. An alien criminal who of course speaks flawless English has somehow dug out a cave in the desert, and after commandeering the body of a scientist, hopes to take over the planet, enslave a large workforce, and use this to create a fleet of starships to return to his own world to take that over. But this guy is so powerful, one wonders why he needed to come here instead of just do it. Fortunately, an alien lawman is in hot pursuit, he aims to stop Gor by enlisting the services of his victim's love interest. And her dog.
Can they stop this fiend before his dastardly plan comes to fruition? What do you think?
