Millie is convinced the world is unfair and her parents make her do most of the work. She isn't allowed to do anything she wants, like watch unlimited TV, chat unsupervised on the internet, or go to that park by herself. Her teachers are unfair, too, and her brother and sister seem to get away with everything.

Millie finally hits upon a plan that will solve all her problems; run away from home! With money stolen from her mother's purse, she buys a bus ticket for big city where she can live as she always wanted. The city sparkles as Mille starts her adventure with ice cream and a trip to the amusement park, but when Millie's money runs out, things dramatically change. Millie ends up scared, no food to eat, and nowhere to sleep. After getting caught stealing, the police notify her parents. Millie finally learns to appreciate what she had and becomes the happiest girl in the whole world.
