All-American space hero Flash Gordon (played by Larry "Buster" Crabbe) once again does battle with the devious Ming the Merciless (Charles B. Middleton) in this vintage sci-fi adventure. Ming has, as usual, set his sights on conquering the Earth, and has designed a new weapon with this in mind -- a special metallic substance that will burst into flame in our atmosphere. After testing this on Arboria and laying waste to Prince Barin (Roland Drew) in the process, Ming heads for Earth; to see that his nemesis Flash will have other things to do as he launches his attack, Ming kidnaps Gordon's best girl, Dale Arden (Carolyn Hughes). Will Flash and Dr. Zarkov (Frank Shannon) be able to rescue Dale, stop Ming, and save the Earth all at once? Perils From the Planet Mongo was adapted from the popular 1936 serial Flash Gordon Conquers the Universe; the 12-episode serial was edited to the length of a conventional feature for sale to television in the mid-'60s.
