Upon arriving to the planet Jinto and Lafiel discover that the planet was used by the United Mankind as a prison planet and now has a million prisoners on the only inhabited island. The prisoners are parted in three blocks. The western where women are housed, the eastern belongs to the men and the central is mixed under the restriction that all prisoners living there are sterilized. The women in the western sector want to emigrate from the planet of fear for the men and when they do the men in the east rebel, overthrowing the guards and capturing Jinto to try to stop the emigration of the women.
