Katherine Heigl (TVs ROSWELL) and Danielle Harris (URBAN LEGENDS) portray sisters Alexa--seventeen, pretty and fashionable, but an average student, and Hayley--fifteen, a smart fashion disaster.

While Hayley loves her new social status, Alexa is less than thrilled with her new place in the school social heirarchy. This update on past personality switching films such as FREAKY FRIDAY and VICE VERSA offers plenty of laughs the whole family can enjoy together.
