Documentary about underwater cave exploration in the Yucatan Peninsula of Mexico. The film follows the ATI Cave Exploration Team and features extreme 'no-mount' exploration cave diving. The production of this film has been sponsored in part by The Cleardeep Foundation.

It features some extreme cave diving exploration and stunning imagery. Their goal is to share with fellow divers and the larger public the beauty of these submerged caves as well as the knowledge and attitude required when approaching an activity as risky as cave diving.

The film is quite informative and presents not only beautiful footage but an unique point of view - entertaining for anybody interested in exploring, under or above the water.
