Boyd Jensen goes to Earth for school, only to find that he's been set up and has been deviously banished from his home on Mars. The United States is now run by an offshoot of Catholicism, and, to replenish the Earth after the nuclear wars, has declared "Be Fruitful and Multiply" to be on par with the Ten Commandments. As a result, the U.S. has since then become hugely overpopulated. Boyd is disgusted by the society around him, and in order to survive becomes a successful medical doctor. Eventually, though, he gets to thinking about overturning the government that puts forward such an insane policy.
