  10. Synopsis Story about a young couple living in an overpopulated future where you are required to have a special permit to have a child. They get a little careless, and the wife gets pregnant. If you don't have the permit, your child will be put in cold storage at birth. Later, if you can get a permit, the government will unfreeze the baby and give it back to you. The couple's only hope is for the husband to win a foot race whose first prize is an acre of land and a baby permit. All of the other competitors have agreed that if they win, they'll sell the land to a Big Corporation. The husband won't sell, so the Big Corporation does various underhanded things to prevent his winning.
