Thousands of years before the Inca, a megalithic civilization was founded at Lake Titicaca which spread 500 miles to Cuzco, following a global flood that destroyed the Earth in 9000 BC. Its architects — Viracocha and his seven Shining Ones — disappeared as mysteriously as they appeared, yet the legacy of temples they left behind still baffles the modern mind. Filmed at Tiwanaku, Puma Punku, Cuzco, Quenqo, Saqsayhuaman, Amuru Machay, Quillarumiyoc, Pisac, Tombomachay, Huayna Picchu, Ollantaytambo, Machu Picchu, Cutimbo, Silustani and Amaru Meru.
