The East High seniors are super busy leading up to the last few weeks of school before they graduate. They are volunteering at the local community center for their senior project, and are gearing up for a huge graduation party at the Lava Springs Country Club!  And Sharpay couldn't be more excited--she gets to direct a musical for her volunteer assignment! But when her production needs a major overhaul and Taylor and Chad stop speaking, the rest of the Wildcats realize that they need to work together more than ever!
