Throughout the centuries, countless explorers visited Patagonia and reported sighting giants. Even the name Patagonia (Land of the Big Feet) speaks to these apparitions. But what exactly did these explorers see?
This documentary accompanied paleontologists, naturalists, and crypto-zoologists on a search to determine whether an extinct, upright-walking ground sloth could have lived into the era of human habitation and spurred these tales. He treks across glaciers, descends deep in the mountain caves, accompanies a band of gauchos on horseback, and joins a modern-day paleontology dig trying to uncover evidence that the ground sloth still exists today.
