Master diver Frank McGuire leads a team - including his 17-year-old son - to explore the largest, most beautiful and least accessible cave system on Earth. But, when a tropical storm cuts off their only escape route, the team must work together to find their way through an uncharted and dangerous underwater labyrinth to make it out alive.
