"It was 75 years ago when Colonel Percy Fawcett and his two young companions, his son Jack and their friend Raleigh Rimmel mysteriously disappeared during the Eighth Expedition into the Brazilian wilds looking for a long-lost ancient civilization of clothed white Indians, a civilization with marvelous underground cities made with advanced technology hidden in the remote jungles; cities greater than those of the Inca Empire; cities with ruins more ancient than the oldest Egyptian discoveries; cities with buildings with a strange source of light that filled with terror the Indians who have seen it; cities inhabitant by subterranean beings hidden in the Mato Grosso area and talking an unknown language. Beings who appeared to be 20 years old, speaking many dialects and Portuguese and said that they were in life more than 2500 years."
