Since most of Camp Rock's staff has left, Mitchie and her gang of friends who have stayed behind take it upon themselves to be Camp Rock counselors. At first, the new counselors struggle to keep up with their new schedules, and Shane becomes frustrated that he and Mitchie aren't spending enough time together. But eventually everyone finds their niche. When discussing the future of Camp Rock, Mitchie and her friends plan a musical showdown between the two camps at Final Jam. Camp Star agrees as Axel suggests they should challenge each other to Camp Wars, a musical showdown being broadcast live on TV. Axel texts and tweetsevery mobile phone in the western hemisphere persuading people to vote for Camp Star.
Although Camp Rock put their heart and soul into their performance with Shane and Mitchie singing lead vocals, the rest of the campers as dancers and musicians, and a video made by Trevor (Frankie Jonas) of their time together airing during the song, Camp Star wins (most likely due to Axel's biased ad campaign) which leaves Mitchie and her friends devastated as it means that Camp Rock will now have to close down. Despite the loss, Camp Rock's performance earns great applause from the crowd and Tess is shown to feel bad about the win as she knows Camp Rock deserved it. The remaining Camp Rock staff and campers return to Camp Rock and gather and sing around the campfire one last time together. As they enjoy themselves, many of Camp Star's campers including Tess and Dana show up having seen the bonfire and ask to join in. Shane and Mitchie share a kiss. Led by Tess, some members of Camp Star except Luke request to go to Camp Rock the next summer because it is much more fun than Camp Star, meaning that Camp Rock will have enough campers to stay alive for another summer.
