In order to protect Grant Demarest from a siren named Margot, Stuart Ames attempts to disillusion him about the girl. Margot threatens to kill herself; Grant reaches for the gun and is accidentally shot. Blaming himself for his friend's death, Stuart books passage on a liner, where he meets Rene, the daughter of a dishonest dealer in gems. They are shipwrecked, and Rene returns to the United States, becoming the guest of Margot, her childhood friend. Rene is later lured to a wilderness cabin by Dysart (an accomplice of Rene's father who is disguised as a count); he attempts to assault her, and Ames, who has followed them, knocks him over a cliff. Ames and Rene make plans to be married.
