The Incredible Journey of the Butterflies

Every year, 100 million monarch butterflies fly 2,000 miles to reach a tiny area high in the mountains of Mexico. Scientists are still puzzling over how the butterflies achieve this tremendous feat of endurance and precision. NOVA flies along with the monarchs, visiting the spectacular locations they call home, and meeting the dangers they encounter along the way.
