Synopsis

Prologue: Infected vampire blood was carried to earthmillions of years ago by the Tubaton, vampire men from a distant galaxy.

Dr Rynning [John Carradine], an aging scientist, is leading a space expedition intoSpectrum, an unknown solar system that he discovered. Along the way, theXB-13 runs into a meteor storm and loses contact with ground controllers,Dr Manning [Robert Dix] and his assistant Valerie [Vicki Volante]. Fortunately, neither Dr Rynning orany of the crew, which includes Comnander Steve Bryce [Bruce Powers], Captain Bob Scott [Fred Meyers],Willy [Joey Benson], and Linda [Britt Semand], are hurt, but the XB-13 is forced to make an emergencylanding on an unknown planet in order to make repairs. Fortunately, theplanet on which they land has an atmosphere exactly like earth, with theexception of some chromatic radiation that makes it change colors.

While Dr Rynning waits in the spaceship (he has a heart conditionthat could cause him to experience a coronary attack in the newatmosphere), the rest of the crew goes exploring. The planet seems to beinhabited solely by prehistoric creatures until they happen upon twogroups of cavemen who appear to be fighting each other. Suddenly, a girlwearing a white skin (that looks amazing like a prehistoric bathing suit)runs past them, screaming as she is chased by three of the cavemen. Willytackles her and, while the girl is knocked out, Linda implants a"communicator" in her brain so that she can understand and speak English.When she comes to, she identifies herself as Malian [Jennifer Bishop] and tells them thestory of her people, the peace-loving Tagani, who are hunted by theblood-thirsty Tubatons. At this very moment, the Tagani are engaged in afierce battle with the Tubaton, from whom Malian was running.

Meanwhile, Manning and Valerie are having sex. Attached to theirheads are electrodes that lead to a machine with a lot of multicoloredtubular lights, a machine that supposedly give the best sex ever.Unfortunately, Manning is too worried about the XB-13 and promises toreturn a bit later and, this time, turn the machine up to the highestsetting.

Malian mentions how some of the Taganis are trying to get to the cavewhere they can get the "firewater" needed to keep their protective firesgoing. Cmdr Steve thinks that "firewater" might refer to petroleum, whichRynning says can be distilled for rocket coolant, so Malian leads them tothe cave where they fill two canisters that Cpt Bob has brought from thespaceship. Steve and Linda then carry the oil back to the ship, whileWilly and Bob attempt to return Malian to the Tagani. However, Maliandoesn't want to go back to the Tagani without Willy. As Willy and Malianare saying goodbye to each other, Bob is attacked and killed by a Tubaton.Willy and Malian try to make it back to the ship, but Willy suddenlypasses out.

Rynning orders Steve and Linda to immediately return to theship. It's a matter of life or death. Steve sends Linda on but goes backto find Bob and Willy. Along the way, he meets with Malian who leads himto dead Bob and passed out Willy. Steve carries Willy back to the ship,where Rynning informs them that their blood tests reveal that the whitecorpuscles are devouring the red corpuscles due to a deadly virus in theplanet's radiation-polluted air. All the people on the planet are doomed.Fortunately, the virus can't survive in the clean air of the earth, but itis necessary to immediately leave the doomed planet.

"This was a highly civilized and brilliant society at one time. Itwasn't enough for them. Not only did they have to acknowledge having suchweapons...they had to use them. I have no doubt we'll be equally brilliantone day." --Dr Rynning
