At the end of their freshman year, all the members of the Wildcats are ready for a wonderful summer vacation. Sharpay (Ashley Tisdale), who has been secretly in love with Troy (Zac Efron), uses her father's influence to help Troy get a job in the luxury club run by her family, and the opportunity to get him a college basketball scholarship. The condition is that Troy must give up the Wildcats and partner with Sharpay to participate in the club's annual talent competition. At the same time, this is also Sharpay's plan to keep Troy away from his girlfriend Gabriella (Vanessa Hudgens). But Troy lets Gabriella be hired by the club at the same time, which makes Sharpay very angry. Sharpay's brother Ryan cooperates with the Wildcats without Troy to rehearse the repertoire for the competition. Unexpectedly, Sharpay found out and forcibly disqualified them. Gabriella sadly resigned from the club, and began to have a rift with Troy, and the wildcats members began to exclude Troy. Which side should Troy choose this time? What different choices will there be this summer?
