National Geographic: The Pirate Code - Real Pirates

Amid historical accounts of piracy on the high seas - of ancient buried treasure and devastating shipwrecks - virtually nothing claims as much intrigue as the destruction of the Whydah Galley, a vessel loaded with a reported four and a half tons of treasure, that went down off the coast of Cape Cod on April 26, 1717. The final resting place of this loot has eluded scholars, historians and treasure-seekers for hundreds of years, but in this release, salvage researcher Barry Clifford embarks on one final, courageous and daunting quest to locate the remains of the vessel that belonged to the ill-fated pirate known as Black Sam.
