The Space War to Decide the Fate of All Mankind!
In Japan, scientifically advanced invaders from the war-destroyed planet Mysteroid cause an entire village to vanish, then send a giant robot out to storm the city by night, after which they request a small patch of land on Earth and the right to marry earthling women, claiming to be pacifists. Mankind must decide whether to capitulate or to resist. The nations of the Earth unite in a common cause to fight off an invader from outer space.
