Sacrificing love and college, Ruth leaves Trace, her fiance, her father and his ranch in Colorado, and with her brain-damaged baby sister seeks help in the hospitals and therapy centers of Denver. Her faith and diligence are repaid as Little Bit slowly improves. But Ruth learns an important lesson in her work at the therapy center. Unable to cope with many of the more severe cases, she gains a new perspective on Trace's feelings about Little Bit. At the same time, on his visits to Denver, Trace begins to see something of Little Bit's individuality. Happily Ruth submits to her long suppressed affection for Trace and the two come closer in a new understanding. Much informative material is provided concerning the needs and treatment of brain-damaged children, but the basic story line reveals too few insights concerning the major characters.
