If you had a chance to meet yourself as an 8 year-old child, would that kid be happy with who you turned out to be? In Russ Duritz's case, the answer is a resounding "NO!" Russ (Bruce Willis) somehow finds his life as a successful "image consultant" turned upside down when he magically meets Rusty (Spencer Breslin) - himself as an 8-year-old child. Rusty is a sweet, but slightly geeky, pudgy little kid who is not at all happy with who he turns out to be - a 40-year-old "loser" without a wife or a dog. Ironically, the kid helps Russ to learn about himself and remember his dreams, in order to become the grown-up he wants to be.
