Wealthy Alan Ashley, blinded in World War I, returns home to face a challenge to his ability to run the family business. As the case goes to court, he is drawn to the cheerful, ever-optimistic Lenore Seldon, his defense attorney's secretary. When he wins his case, he offers her employment, but she declines and disappears from his life. Ten years later, frail and in desperate need of work, Lenore answers his ad for a personal assistant. He hires her with the agreement that she will live in, chaperoned by his housekeeper, so that she can drive for him, and he can teach her to use the Braille writer. She is the perfect employee, but he senses that she is frightened of something-or someone. When he finds himself falling in love with her, he must uncover her secrets in order to save their relationship---and to save her from herself.
