After his young wife dies, Phillip Fletcher, a millionaire and sculptor, makes his home on an uncharted desert island. Harry LeRoy, a cad who is courting the widow Mrs. Hansen, desires the widow's convent-bred daughter Norma and persuades mother and daughter to accompany him on a sea cruise. When the ship catches fire, Norma, abandoned by LeRoy and her mother in the confusion, is washed ashore on Phillip's island. Phillip clothes and shelters Norma, whose mind has become childlike from shock, and uses her as a model for his sculptures. Through Phillip's friend Jack, a photo of one of the sculptures travels to America, where LeRoy sees it and subsequently finds his way to Phillip's island. LeRoy tries to rape Norma, and in the ensuing struggle LeRoy is killed and Norma recovers her adult personality.
