This is the story of the men and women who risked everything to find the deepest cave on Earth, earning their place in history beside the likes of Peary, Amundsen, Hillary, and Armstrong. Tabor focuses particularly on the heroic efforts of Bill Stone in the vast Cheve Cave of southern Mexico and Alexander Klimchouk in the supercave Krubera of the Republic of Georgia.

Stone -- Klimchouk -- Game over.
