Explore the mysterious world of the underground: the world’s most remote, unexplored caves. Follow two female cavers as they search for extreme living organisms in the ice caves of Greenland, the underwater caves of the Yucatan Peninsula, and the earth caves of the Little Grand Canyon. Featuring unprecedented footage from unique and forbidding ice caves, underwater caves, and terrestrial caves.
Wriggle through tiny, twisting passages, drop into gleaming blue labyrinths of ice, swim through flooded underground vaults, and enter a world so extreme the microscopic creatures who live there are called extremophiles. Circle the globe, stopping in the hot, lush Yucatán; dropping into barren, frozen Greenland and flying above the primitive red rock Arizona desert. And hold your breath as expedition leaders, Dr. Hazel Barton and Nancy Aulenbach, rappel down steep cliffs into unmapped chambers, hoping to bring back startling new discoveries that may unlock new cures for human disease.
“…the most beautifully exotic locations on the planet.”

“It is a breathtaking sight…an engrossing look into the earth’s secret places.”
“…more than delivers on its title's promise. The challenges of [the caves] are formidable, and their beauty on the big screen is breathtaking."
“One of the best IMAX films…an always engrossing, often enthralling trip into the beauties, and all-too-frequent dangers, of cavern exploration."
—Santa Monica Daily Breeze.
