Start backstage before the concert. Then you see Hannah sing 'Rock Star.' The Jonas Brothers come onstage to sing with the Hannah, and then by themselves. While they are performing, Hannah goes backstage and switches to Miley. Compared to Hannah's songs, Miley's are a little edgier, slightly sexier, as she sings the sisterhood anthem 'Girl's Night Out,' and the flamenco-inspired 'Let's Dance.' She sits down to sing and play guitar to 'I Miss You,' a touching tribute to her late grandfather. Interspersed are rehearsal segments, Miley and her dad traveling together to the studio and later singing a duet at home, Miley's mom describing how she helps her daughter change clothes backstage, and fans and their dads saying why they like Hannah/Miley.
