At the end of their freshman year, all members of the Wildcats are ready for a wonderful summer vacation. Sharpay (Ashley Tisdale), who has a long crush on Troy (Zac Efron), uses her father's influence to help Troy get a job at the luxurious club he runs 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 Gabriela (Vanessa Hudgens). But Troy let Gabbylla be hired by the club at the same time, which made Sharpe very angry. Sharpay's brother Ryan worked with the Wildcats who lost Troy to rehearse songs and participate in the competition. Unexpectedly, Xia Pei found out and forcibly revoked their qualifications. Gabrilla sadly resigned from the club and began to have a rift with Troy, and members of the Wildcats began to exclude Troy. Which side should Troy choose this time? What different choices will there be this summer?
