Millie Bird, seven years old and ever hopeful, always wears red gumboots to match her curly hair. Her struggling mother, grieving the death of Millie's father, leaves her in the big ladies' underwear department of a local store and never returns. United at this fateful moment with two octogenarians seekers, she embarks with them upon a road trip to find Millie's mother. Together they will discover that old age is not the same as death, that the young can be wise, and that letting yourself feel sad once in a while just might be the key to a happy life.
