In 19XX, experiments with new bombs devastate the earth completely. The only survivors, a Japanese expedition team to Venus, returns to the earth to witness human beings dying of radiation sickness. The crews try to save the humans, but they are not fast enough. The captain of the team thinks about moving to Venus by discarding the earth, but Kuroda and Yasuki, the crews, rise in revolt against him and aim to become the rulers of the earth by obtaining the weapons of the world.
