Now high school seniors, Troy Bolton (Zac Efron) and Gabriella Montez (Vanessa Hudgens) are facing the prospect of being separated from each other as they go off in different directions when graduating from East High. Joined by the rest of their Wildcat friends, including Sharpay Evans (Ashley Tisdale), Ryan Evans (Lucas Grabeel), Chad Danforth (Corbin Bleu), Taylor McKessie (Monique Coleman) and Kelsi Nielsen (Olesya Rulin), they stage an elaborate spring musical reflecting their experiences, hopes and fears about the future.
