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?
