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 Ñ 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."
