Lying at the foothill of Peru's Andes Mountains is the site of one of the world's greatest mysteries. Etched, as if by giants, onto its arid, moonscape plains are immense lines that stretch for miles to form strange shapes recognizable only from the air. Forming the shapes of animals, plants and humans, they were first spotted by pilots in the 1930s, and inspired fantastic explanations ever since and scientists have long speculated about their meaning. Now, a team of specialists from around the globe has come to southern Peru to investigate the Nasca Lines in the hope of uncovering their secrets. Thanks to intensive excavations, new technology and the findings of Italian, Peruvian, French and American scientists the film will help us shed light on the mystery that shrouds the strange and puzzling world of the ancient Nasca and Paracas, an older culture located on the southern coast of Peru in the regions of Ica and Nasca.
