Master diver Frank McGuire has explored the South Pacific's deep underground Esa-ala Caves for months. But when his exit is cut off in a flash flood during a hurricane, Frank's team—including his 17-year-old son Josh and financier Carl Hurley—are forced to radically alter plans. With dwindling supplies, the crew must navigate an underwater labyrinth to make it out. The unavoidable question: Can they survive?
