"The Wildcats are back," reads an announcement for the sequel. "This time, school's out and East High School hoops star Troy Bolton, A-student Gabriella Montez and the rest of the Wildcats are getting ready for a fun summer vacation. But that all changes when scheming drama queen Sharpay Evans uses her dad's connections to get Troy a job at their ritzy country club — and a chance at a college basketball scholarship. The catch? He'll have to turn his back on his friends and pair up with Sharpay in a musical extravaganza for the club's annual talent show. But when Gabriella and the Wildcats start making plans without Troy, he must decide where his loyalties truly lie."
Kenny Ortega ("Newsies"), who both directed and choreographed the original film, returns for the sequel, which was penned again by writer Peter Barsocchini. Songwriters for the sequel include Matthew Gerrard, Robbie Nevil, Jamie Houston, Tim James, Antonina Armato, Randy Petersen, Kevin Quinn, David Lawrence and Faye Greenberg. Lawrence also composed the score for the movie.
