Macy Misa is the biggest JONAS fan out there. She also happens to go to school with the boys, plus she's best friends with Stella, the band's stylist. But every time she's around Joe, Kevin, and Nick, her nerves take over! When Macy overhears Kevin saying that the band needs a backup singer for their next album, she eagerly volunteers. After a test run, however, Kevin realizes that Macy's singing isn't record material. Will Kevin risk hurting Macy's feelings and tell her the truth, or will he put his band on the line and let her sing?
