High school students Olivia White, Mohini "Mo" Banjaree, Charles "Charlie" Delgado, Stella Yamada, and Wendell "Wen" Gifford all meet after ending up in detention for different reasons. Miss Reznick, the music teacher supervising detention, leaves to argue with the principal Mr. Brenigan about his decision to move all extracurricular activities to the basement to make room for a new gymnasium. The five then tap out a beat and play instruments, and Olivia sings "Turn Up the Music." Miss Reznick returns and says that they would make a great band, and encourages them to enter a music competition called "Rising Star," in which a popular band, Mudslide Crush, planned to enter.
