An American ship is wrecked off the coast of the Dutch East Indies, and little Faith Fitzhugh and her mother have washed ashore on a rocky island that supports only a lighthouse. Faith's mother lives only long enough to inform the three Dutch lighthouse keepers that her daughter is the heiress to a large fortune. Years pass and Faith grows to womanhood. Jacob Kroon and his son, Piet, then conspire to marry Faith to Piet's idiot son, Hans, in order to bring her fortune into the family. Dick Wayne, a sailor on an American cruiser that is repairing a damaged cable in the waters of the lighthouse, learns of Faith's captivity and comes to her rescue. Piet kills Jacob in a fit of jealousy, and Dick then kills Piet in a fight. Hans sets the lighthouse on fire and incinerates himself. Dick and Faith make it back to the cruiser.

They have a child, but family life is interrupted by the gambler Ringe, who not only persuades Nelly to leave her husband but ruins Sierra at the gaming table. With thoughts of vengeance, the angry Sierra breaks out of jail and goes after Ringe.
