With the Galaxy under attack, Princess Farra and her beautiful bodyguard flee to a strange alien planet - Earth. They are pursued by the evil Empress and her henchwoman.

Princess Farra has summoned the Vulvian Empress Krella to Planet Byfrexia, hoping their advanced technology can suppress the torrential rains ravaging their world. But Krella employ the invitation as an excuse to plan an invasion instead. As the initial battle erupts, Farra and her attendant Vema flee at hyper-light speed until their ship loses power. They land on Earth, which happens to be nearby as they break down. They search for a replacement part for the disabled ship, stumbling onto the isolated residence of Jock in the process. Their arrival has been witnessed by Mark, who has also suffered a breakdown and is working on his car on an isolated roadside. When he calls into authorities to report an unusual craft crashing in the woods, two special agents in black, Smith and Jones, show up to investigate. They find the location where Mark indicates the ship came down, the radiation surrounding the cloaked ship affects everyone's libido. About that time Krella's commander Tharis and UFO enthusiast Will arrive on the scene.—Garon Smith
