When the principal of Bayside decides to make all the students wear uniforms, Raven organizes a protest. But when the students don't stand behind her, Raven finds herself in detention with the only people who did: the school bullies. Plus, when spending the afternoon at a spa, Raven disguises herself as a yoga teacher to get an autograph from her favorite pop singer.
