MacMurray is an honest trader trying to amass a fortune in the Dutch East Indies. He comes across a diamond fortune and buys Ralston, a Javanese dancer. Later, to make things legal, he marries her. The antagonist is Douglas, who is cast as both a backstabbing pirate and an honest
Dutchman trying to get his hands on the stones. MacMurray, in his admirable way, continues on to make his fortune, even though the diamonds are lost to the sea when a volcano erupts. Songs include "Bound for the Open Sea" and "Darling Nelly Gray."
