A year after the events of the previous film,Mitchie Torres(Demi Lovato) returns to Camp Rock for another summer year along with her friends and the members of the band Connect 3: Mitchie’s love interest, Shane Gray (Joe Jonas), Nate Gray (Nick Jonas), and Jason Gray (Kevin Jonas). Along the way, she and her mother, Connie Torres (Maria Canals-Barrera), notice that a new camp, Camp Star, has opened across the lake. Mitchie and her friends also notice that there are fewer campers than last year and attempt to lift everyone’s spirits at the Opening Jam. Camp Star sends parachutes to Camp Rock with chocolates and marshmallows, inviting them to a bonfire at their camp, but Brown Cesario is less than enthusiastic, as Camp Star’s founder is Axel Turner (Daniel Kash), whom he kicked out of his band.
Mitchie and the rest of the campers arrive at Camp Star. The bonfire starts and Axel asks Camp Rock to perform. Mitchie volunteers and performs. After, Camp Star performs. As their performance ends, Dana Turner (Chloe Bridges)’s bracelet flies from her hand and hits Nate in the eye. Axel then offers the Camp Rock counselors jobs at Camp Star, doubling their salary, and encourages the Camp Rock campers to move to Camp Star. Only a few campers switch, including Tess, but many counselors move to Camp Star. Nate returns Dana’s bracelet after the bonfire and the two bond. Dana also reveals she is Axel’s daughter. Left with no staff, Brown is forced to close Camp Rock, but Mitchie persuades everyone to not give up, and she and her friends take on the newly vacant counseling roles.
