an argument between Tess and Caitlyn escalates to a food fight. Tess portrays Caitlyn as the aggressor of the dispute to Brown Cesario, the camp's director and Shane's uncle; Brown punishes Caitlyn by making her work in the kitchen. Mitchie, worried Caitlyn will learn about her secret, does not defend her, to Caitlyn's annoyance. Shane shares a song with Mitchie, which is a stylistic departure to his previous music with Connect 3. Doubtful his record label and fans would accept a change in musical direction, Mitchie expresses she likes the song. As Caitlyn arrives in the kitchen and learns about Mitchie's secret, they argue but reconcile at Pajama Jam, a pajama party music showcase, after Mitchie stands up to Tess when Tess attempts to upstage Caitlyn's performance. Jealous at seeing Mitchie and Shane together, Tess follows her and learns of her secret. Tess exposes Mitchie in front of campers; Shane, believing Mitchie lied to him solely to be with him because he is famous, breaks their friendship and Mitchie becomes ostracized at camp. Tess then deduces Mitchie is the mysterious singer. On the eve of Final Jam, Tess frames Mitchie and Caitlyn for stealing her bracelet, and Brown bans them from all camp activities until the end of Final Jam. At Final Jam, which is judged by Connect 3, Peggy and Ella argue with Tess and opt not to perform with her as planned; Ella performs with fellow campers Barron James and Sander Loyer. Tess stumbles during her performance after TJ attends and takes a call. Peggy performs a solo song as Final Jam's closing act and eventual winner. When Brown announces the end of Final Jam, Mitchie and Caitlyn make the spotlights flicker; he lets them go on stage, proud they understood their ban was only until "the end of Final Jam". As Mitchie sings, Shane realizes she is the mysterious singer, and they reconcile by singing together. Backstage, Tess apologizes to Peggy and Ella and tells Brown that she staged the theft of her bracelet. In the extended ending, Caitlyn invites Mitchie, Tess, Peggy, and Ella to the recording studio she built in her garage. Cast Demi Lovato as Mitchie Torres, a young girl aspiring to be a singer.
