One of the world's top wildlife photographers, Cyril Ruoso, is partnered up with a scientific journalist for an adventurous journey through three of the most extreme ecosystems on our planet, the impenetrable rainforest of the Amazon, the sky scraping glaciers of the Andes, and the desert plains of the Pacific Coast of Peru. During their search for rare and uncommon species, they meet with scientists and discover what links all three ecosystems together. Finally, they understand the need to preserve them when climate change and human activity are threatening their very existence.
