They soon find a strange underground world where the laws of science are turned upside down. They discover huge caverns, luminous rocks, a subterranean sea, primitive forests, and fearsome prehistoric creatures. The travelers encounter one stirring adventure after another as they explor deep within the bowels of the earth and then try to make their escape.
