A deadly disease swept through America. It struck suddenly and mysteriously. Thousands would die. Many more would be left helpless. The disease was poliomyelitis. Polio would enlist renowned scientists, shape the vision of one of the world's greatest leaders (Franklin Roosevelt), and transform a young unknown doctor (Jonas Salk) into a world-famous hero. Ingenuity, trial and error, even acts of scientific desperation would pave the way to one of the greatest breakthroughs in scientific history.

Many rivers quenched the thirst of millions in the American west and around the world. Without these aqueducts, some of the earth's largest cities would turn into gigantic ghost towns.

Aqueducts have made some men famous and others fabulously wealthy. In Los Angeles one man's vision took one hundred thousand men to complete and a great city was truly born. In Northern California the most famous conservationist of our time waged the political fight of his life in an attempt to save one of nature's most spectacular valleys from San Francisco's demand for more water.
