This is a remake of a 1936 sci-fi, future dystopia tale by H.G. Wells, but the drama, as interpreted by director George McCowan and scripter Martin Lager is not altered to accommodate today's more demanding audiences. As a result, the story, characters, and dialogue are a little weak. After a nuclear holocaust has forced people on earth to set up house on the moon (covered by an insulating, glass-like bubble), their continuing existence depends on some medication to fight off the effects of radiation (!). The trouble is that this medicine is now controlled by the villainous Omus (Jack Palance) who lives on the planet where the miracle drug is made. He is in the process of blackmailing the earth people into accepting him as a dictator when a group of them sneak out in a rocket to defeat him and save the day, whatever the day is on the moon.
