Adventure, by Fritz Lang, Germany, 1919.
In San Francisco, Kay Hoog tells friends at her club that she found a message in a bottle. Inside is a map drawn by a missing man, a well-known Harvard professor. The message tells of a lost Inca civilization that possesses an immense treasure.

Food for thought
The outer treasures pave the way for the inner treasures. Once you are rich on the outside you need to look for the wealth that you still lack, the inner wealth. It is difficult for a poor person to take an interest in his interiority before solving his basic needs. But a rich person has no choice, he has to take that path.
