Dr. Theopolis is negotiating with Mr. DeBronin from the planet Ruatha to continue to explore barbarite, a necessary mineral, on the planet Madrea that is dominated by the Ruathan. Meanwhile, Buck Rogers receives a distress call from two attractive women from the planet Zantia telling him that their ship is stranded in the space. Zantia is a closed planet forbidden to other species, but Buck Rogers uses his starfighter to tow their ship and is authorized by the flight control to land. Buck is introduced to their uncle, Cassius Thorne, and soon he learns that he was lured. He is sold as a sexual slave to the Prime Minister's daughter Ariela Dyne and soon he learns that Zantia has only a few men. The reason was a war with Ruatha, when most of the warriors have been murdered or captured. Further, Buck Rogers note that Zantia is abundant in barbarite, and he decides to help Ariela to meet the Ruthian diplomat.
