It's almost graduation day for high school seniors Troy, Gabriella, Sharpay, Chad, Ryan and Taylor — and the thought of heading off in separate directions after leaving East High has these Wildcats thinking they need to do something they'll remember forever. Together with the rest of the Wildcats, they stage a spring musical reflecting their hopes and fears about the future and their unforgettable experiences growing up together. Will their final show break them apart or bring them together for the greatest moment in Wildcat history?

Troy, the popular captain of the basketball team, and Gabriella, the brainy and beautiful member of the academic club, break all the rules of East High society when they secretly audition for the leads in the school's musical. As they reach for the stars and follow their dreams, everyone learns about acceptance, teamwork, and being yourself.
