In 1944, near the end of World War II, the Japanese submarine I-52 -- carrying cargo to Nazi Germany -- was torpedoed by American bombers. It sank to the bottom of the Atlantic Ocean, taking with it 100 people and two tons of gold. Half a century later, Paul Tidwell, a Vietnam veteran and adventurer, set off on a hunt for the sunken submarine in hopes of unraveling the mystery and salvaging the gold. As part of his research, Tidwell got in touch with the men who participated in the Navy's sinking of the submarine; they joined the expedition and recount their memories on film. The production includes dramatic shots of the broken remains of the sunken sub three miles underwater, along with scenes that show the numerous perils and tensions involved in carrying out this historic expedition.
