Jenna (Jennifer Garner) was 13 years old and wishing she could be one of the cool kids. At her 13th birthday party, after being mocked and rejected, she hits her head and some magic dust falls on her as she wishes she could be 30. When she wakes up, her wish has come true. She learns that she was accepted by the 'cool' group, but rejected her best friend Matty and lost touch with all the things and people she loved as a kid. She is now a high-powered magazine editor with loose morals! She takes steps and tries to fix her broken life, because she doesn't like who she became. This movie is kind of a mix between Big (Tom Hanks) and Freaky Friday.
