A Disney Channel Original Movie. It's about a girl named Mitchie Torres (Demi Lovato) who goes to a music camp during the summer. There, she meets a pop star (Joe Jonas). She sings a song that inspires him. He falls in love with her. Meaghan Martin and Alyson Stoner also star.
Alpha Bitch: Tess, one of the most over-the-top examples. Hell, she even sings a song with lyrics like "I'm too cool for you" and "You see, some are born with beauty, brains, and talent, and they got it all".
Backstabbing the Alpha Bitch: Peggy and Ella get tired of Tess's domineering attitude near the end of the first movie and leave her to do her performance alone. Unlike most examples, they eventually forgive her.
Billing Displacement: The Jonas Brothers were billed equally in the promos for the first film, despite the fact that Nick and Kevin only played minor characters. It's toned down in the second film where they get bigger parts and Nick's character even gets a love interest.
The Cast Showoff: To be expected, obviously, but notable moments include Joe Jonas playing guitar (which is a very rare occurrence) and dancing, especially as he has no former training in the latter and his brothers do most of the guitar-playing at shows.
Chekhov's Gun: Minor example in the second movie. Early on Mitchie's mom bemoans the accidental delivery of dozens of inflatable balls. The group use them later in their performance, unleashing them on the audience.
You kind of feel sorry for whoever had to blow them up...
Deus ex Machina: Seriously now, Camp Rock is spared from being closed down because Camp Star doesn't have any campfires? I know they had to have some way to keep the antagonists from winning completely, but let's be real....
This is justified and lampshaded by the song 'This Is What We Came Here For', in that while kids like Luke (and Tess) are dedicated towards having a musical career, most of the campers from both camps are simply average kids who have some musical talents and wanted to go to a summer camp where they could also play music.
It was probably also because Axel is a jackass. Most of them probably decided they'd had enough of him.
Evil Counterpart: In the second film, Luke for Mitchie, and Axel Turner for Brown.
Freudian Excuse: Tess, whose mother is always working. Her mother came to see her in the competition, then walked out on her when she was performing.
Jerkass: From the first film, Shane during the first act and Tess in both movies.
Karma Houdini: Tess basically bails on her friends for glitz, glamour, and air conditioned cabins. Keep in mind, these are the people who forgave her after she spent a whole movie treating them like crap, welcomed her as a friend with open arms, and never spoke of her previous unpleasant behavior again. She suffers no consequences for ditching them like that and leaving Camp Rock to flounder. Even though she makes a Heel-Face Turn at the end (yes, again), it doesn't really do much to take the sting out of that.
Mood Whiplash: In one scene Mitchie is shown going around complaining that no one is working hard enough. Everyone protests that they are, they're just taking a break, and the implication is that she's slave driving them. Peggy even says "I love her, but I'm going to kill her." The very next morning, Mitchie wakes up to discover that everyone has come around to her way of thinking and have been practicing for hours.
Name's the Same: Tess Tyler, which was also an Olsen twins character in one of their movies.
Well Done Daughter Girl: Tess. The reason for most of her Alpha Bitch behavior in the first film was to be good enough that her Mom would finally pay attention to her. It hits her pretty hard when her Mom finally shows up to one of her shows and then walks out on her to take a phone call.
