The beginning of the film deals with the love romance of a deep-sea diver and the daughter of an old curio collector, whose past life takes up a good part of the film and reveals to the spectator his younger days as he tells them the story of his romance and marriage. The dramatic situations, showing how his young bride was stolen from him by buccaneers, his heroic rescue of her, the casting overboard of the treasure chest and the burning of the vessel, prepare the spectator for the climax of this dramatic film when the deep-sea diver goes in search of the sunken treasure. Here is introduced a wonderful scene of the bottom of the ocean with the diver at his work. The frantic struggle for air when the pumps are stopped, the finding of the treasure and the saving of his sweetheart's father are all intensely interesting.
