Brothers Taylor and Granger are New England whaling captains but Granger decides to treasure hunt instead. He finds a priceless cache of black pearls on an island but angers the locals who regard the gems as sacred. When Taylor rescues him, Granger promptly turns his brother's crew into mutineers in order to return to the island and retrieve his prize. Lots of brawling and there's an incidental love story with Blyth desired by both men (she's married Taylor and just happens to be aboard). Last role for Stone. Based on the novel by Ben Ames Williams.
