Jeff Corwin joins an elite hit squad of scientists on an adventurous mission to search out new species in one of the most remote and mysterious regions on Earth - the Himalayas. The mysterious Makalu-Barun National Park, on the shoulder of Mount Everest in Nepal, is a “biodiversity hotspot” - a rugged, forested region that Conservation International has singled out as the destination of an extraordinary expedition. Working day and night, a team of CI scientists will build an inventory of the region’s wildlife. They hope, and expect, to come across new species as they work. Makalu-Barun is also a hotspot for yeti sightings. While the CI scientists work day and night, Jeff undertakes his own mission: to search out another, undescribed species - the infamous yeti. Determined to get to the bottom of this enduring mystery, he is guided by the stories of local people, the words of yeti myth experts, the advice of his fellow biologists and the accounts of holy men. He stumbles upon recent photographs and prized yeti relics, and travels to isolated yeti haunts in his search. By the end of the show, he is ready to draw his own startling conclusion about the truth behind the myth.
