Synopsis by Janiss Garza
Since this film was produced by the Williamson brothers (George and J. Ernest) -- most famous for their work on the 1916 version of 20,000 Leagues Under the Sea -- it's a sure bet that this drama features some impressive underwater photography. J. Ernest Williamson himself supervised the cinematography. After locating a gold mine, Stephen Verrill dies. It is left to his widow and little daughter, who prepare to travel from the West Indies to New York, to make the claim. Mrs. Verrill offers Captain Ross a third interest if he helps her finance a company to operate the mine. But disaster strikes on the voyage as a trader, Matt Cuttle (Alex Shannon), scuttles the ship, which wrecks on an untamed coast. The little girl is washed ashore and since she can't be found, the mine apparently has no heirs. Ownership reverts to the state and Cuttle buys it. Years later, Tom Ross (Chester Barnett), the son of Captain Ross, is determined to prove that his father was not the one who sank the ship. His journey takes him to the coast where he finds Verrill's daughter, now a nature girl known as Mimi (Betty Hilburn). He dives in search of the wreck and is attacked by an octopus, but Mimi comes to his rescue, and she also reveals that she has the deed. Cuttle tries to denounce them and then goes after the deed himself. But he must fight Tom to get it and he is knocked into the water, where he is killed by a shark. Tom and Mimi marry and take possession of the mine.
