| Synopsis | In the year 2178, Doctor Fred Gibson is on frozen Jupiter and searching for his fiance Elsa. His romantic rival, archeologist Phil Travis, finds her first but lacks the medical knowledge to treat her properly. Gibson, however, finds ancient Jovian technology that telepathically reveals its history: Jovian scientist Halfar Kal invented a "Droga Ray" that artificially evolved the Jovians into pure energy, allowing them to travel throughout the galaxy. Gibson uses the ray on himself and -- as an invisible energy being -- helps Travis save Elsa. Travis returns to Earth, but the grateful Elsa opts to stay with Gibson, her true love, who used the ray a second time to return to normal. |
