After years of giving of herself to her family and community, Grace Beiler, an elderly Amish woman, is facing her first Christmas since losing her husband of fifty years to his battle with cancer. As she begins to reflect upon her own life, she wonders if she has properly fulfilled her promise to be a servant of God.

With Christmas drawing near, her depression becomes stronger until she starts receiving little gifts in the mail and left on her doorstep. She realizes that she has a "secret sister," but has no idea who it might be, for each gift seems to relate to different, important events in her life. Just when she thinks she might have figured out who the secret sister is, a new gift arrives with a different meaning.

Who is making this Christmas one Grace will never forget?
