Now for the first time, this film presents the history, mythology & folklore that the earth has a hollow realm, a mystical and physical place of great mystery and wonder. The hollow earth theory is represented in the history of many diverse cultures throughout the world. The Avalon of Camelot, the Garden of Eden, Paradise Lost, Shangri-La and Valhalla are names assigned to a mystical and physical place thought by some to house prehistoric animals and plants and by other to hide alien beings bent on conquering the outer Earth. This fascinating program is a compilation of extensive research by the International Society for a Complete Earth.
