It's good when a person has a goal and is obsessed with it throughout their life. Such is Martin Beyerly, a treasure hunter who has devoted his entire life to searching for jewels from the sunken liner RMS Republic.

One hundred and forty thousand people, four thousand four hundred ships, the most formidable fleet in history, and all of it vanished without a trace. But why did it disappear?
