When Mia arrives at her new school, her motto is to be open and friendly with everyone. However, not everyone at Park Street School believes in mixing with different groups of friends. When the Popular Girls Club takes interest in Mia's awesome fashion style and wants to recruit her, Mia has to decide between them and her great new Cupcake Club friends. It's like choosing between her divorced mom and dad and her old house and new house. Is it always going to be Mia in the middle, or can she mix it up?
