Her father, Daniel, has devoted his life to her, with hopes and dreams that her circumstances will change one day. The opportunity comes with the discovery of the worldwide "Doctor's Gift" program. Katie volunteers and comes to China. Once there, she is deeply touched by the work, which prompts her to take off on her own to find Lin. A "smile" is brought to Lin's face, Katie finds her soul and their extraordinary connection becomes a life-changing experience for both girls.
