The novel takes place on a planet where humans have been genetically engineered to be sterile and infertile, with the goal of preventing overpopulation. The story follows a group of rebels who seek to overthrow their rulers and restore fertility to humanity. They discover that the only way to achieve this is by finding a way to break through the "Iron Womb", a technological barrier that prevents humans from reproducing naturally.
