Description: A pilot and his young passenger crash-land on a mountaintop and are put into suspended animation by a strange gas. They awake 500 years later to discover that the Earth is now ruled by a tyrannical despot called Killer Kane, and they lead a fight to overthrow him. Preserved in a state of suspended animation for 500 years by the Nirvano gas in the gondola of their dirigible wrecked in the arctic ice wastes, Buck Rogers (Buster Crabbe) and Buddy (Jackie Moran) are rescued by scientists in the year 2500 to find the world under the despotic rule of Killer Kane (Anthony Warde) and his super gangsters. Using an arsenal of fantastic weapons created in Dr. Huer's (C. Montague Shaw) clandestine laboratory, the group attempts to seek aid from the planet Saturn to oust the tyrannical ruler only to find that his henchmen have already taken over control of the Prince of Saturn. After several harrowing adventures with the Zugg men, Buck and Buddy return to Earth only to be shot down, imprisoned and finally rescued to participate in a spectacular air battle to wrest control of the Universe from the sinister intergalactic despot. Buck Rogers and Buddy Wade are in the middle of a trans-polar dirigible flight when they are caught in a blizzard and crash. Buddy then releases a special gas to keep them in suspended animation until a rescue party can arrive. However, an avalanche covers the craft and the two are in suspended animation for 500 years. When they are found, they awake to find out that the world has been taken over by the outlaw army of Killer Kane. Along with Lieutenant Wilma Deering, Buck and Buddy join in the fight to overthrow Kane and with the help of Prince Tallen of Saturn and his forces, they eventually do and Earth is free of Kane's grip.
