Plot Synopsis

UNTAMED AMERICAS captures the extreme wildlife of North, Central and South America, filmed over two years in subzero temperatures of Alaska, jellyfish swarms in Monterey Bay, offseason hurricanes in the Pacific, the dense underbrush in the Ecuadorean cloud forest, breath-taking high altitudes of Chile, and everywhere in between. Each of the four, 60-minute episodes focuses on a different ecoregion, including: "Mountains," which highlights newly awakened black bears that go on the hunt for newborn elk calves on the Yellowstone plateau and the toughest mating contests on the planet as male bighorn sheep in the Rocky Mountains; "Deserts," which reveals the Humboldt penguins raising their families in the Atacama Desert, the driest place on earth, and tiger moths that dodge millions of hungry bats emerging from caves in the Chihuahua Desert; "Coasts," which documents male gentoo penguins performing mating jigs to attract females at the Falkland Islands and hordes of voracious giant Humboldt squid that cannibalize their kin in the Sea of Cortez off the coast of Mexico; and "Forests," which presents river dolphins hunting along the forest floor when the Amazon River bursts its banks during flood season and an elusive jaguar taking down a caiman crocodile with stunning expertise. This program marks the first U.S. simulcast on National Geographic Channel, Nat Geo WILD and Nat Geo Mundo.
