Argentina is a land of extremes. It's home to the highest mountains in the Western Hemisphere, the largest waterfall system on the planet, and some of the driest places on Earth. And its people and history as varied and remarkable as the land itself. This three-part series takes flight over the country's natural wonders and man-made metropolises, exploring its fascinating stories, places, and people, past and present, from the Pampas to the city of Buenos Aires to Patagonia, and all the national treasures in between.
