SUBMARINE I-52: SEARCH FOR WWII GOLD

It sounds like a Clive Cussler thriller: A Japanese sub en route to Nazi-occupied France is attacked by U.S. warplanes and sinks to the bottom of the Atlantic -- along with two tons of gold bullion. More than 50 years later, a Vietnam vet with a mysterious agenda mounts a series of missions to recover the booty. Mixing a dollop of history, a dash of deep-sea adventure, and an obsessed protagonist who would do Ahab proud, this swell National Geographic doc could have been called What Lies Beneath. B
