It's move-in day at MacKendrick Prep. Among the new students are Jodi and Sun Hi, and a mysterious roommate they have yet to meet. Meanwhile, another freshman, Caleb, looks for a part-time job to accommodate his DJ skills. With advice from the spirit squad captain and resident popular girl, Valerie, he checks out the "super cool" roller rink, which turns out to be anything but. Meanwhile, MacKendrick drama Teacher Mr. Melwood Stark announces that there will be a school musical this year - but states that freshmen never, ever get the lead... a fact that Sun Hi is determined to change. And Jodi and Sun Hi's roommate, Corki, finally arrives - but they don't get any answers about her private life: Corki remains a mystery. Who is she?
