When the ''RMS Titanic'' sinks, infant Dorothy Hunter (Miriam Hopkins) is left an orphan. She is brought up by John Connors (Henry Stephenson), whose wife was also lost in the disaster. He goes to such great lengths to protect her privacy that, though she has grown into adulthood and acquired the title of the richest girl in the world, the newspapers do not have an up-to-date photograph of her. She returns to America, but her friend and secretary, Sylvia Lockwood (Fay Wray), impersonates her in a meeting with the managers of her fortune.
