But, Penelope's mom decides to go and help her dad on a scientific experiment and sends Penelope to live with her aunt and three cousins. Penelope is horrified. She can stand her bratty cousins, but not her aunt. Her aunt thinks that anything and anyone to do with the theater is vulgar and shouldn't be on the earth. Penelope doesn't think she will survive. Then she befriends a girl at her new school, a professional actor next door, and a flamboyant dancer/actress who has a totally different life style then Penelope has ever seen or heard of before. With their help and encouragement Penelope learns to follow her dreams and to never ever give them up.
