High School Musical 3: Senior Year continues the ongoing tune-filled love story between basketball player Troy Bolton (Zac Efron) and brainy beauty Gabriella Montez (Vanessa Anne Hudgens). As they head toward high-school graduation, the couple realizes that they'll be separated when they head to different colleges in the fall, so they join with their friends to produce a spring musical that will help them express their hopes and fears about the future.
