Team captain Troy rallies the team's spirit. They win their last game at East High, thanks to the winning shot from their newest team member Jimmie "The Rocket" Zara. Later, at Troy's after-match party at his house, Troy and Gabriella are seen thinking about their future and wishing that their last few months at East High would not end.
Sharpay meets Tiara Gold, a British exchange student whom she hires to be her personal assistant. When drama teacher Ms. Darbus notices that there were so few sign-ups for the spring musical, Sharpay suggests she could do a one-woman show. This alarms Kelsi, who is writing the show, so she immediately signs up everyone in their homeroom for it instead. This results in Ms. Darbus announcing they will create a play about their final days at East High, called Senior Year. In addition, she reveals that Sharpay, Ryan, Kelsi, and Troy have all been considered for a scholarship at Juilliard School, but only one of them is to be chosen. Troy is confused, because he did not apply to Juilliard. Sharpay becomes desperate to win the scholarship, and knowing that Kelsi will give the best songs to Troy and Gabriella in the musical, she gets Ryan to try to persuade Kelsi to give them a song, by predicting her (and Ryan's) future.
The next day, Gabriella and Troy meet on the rooftop and she teaches him how to waltz. Chad then asks Taylor to go to prom with him with a cheesy pick-up line. She initially refuses due to his lack of enthusiasm, but later agrees when Chad proves he can put in some effort and asks again in front of everyone in the school. The group rehearses for the musical, a scene about their prom night. The next day Ryan walks in on Kelsi composing in the music room and performs it with her, and then he asks her to prom halfway through. While Troy and Chad reminisce about their past when their childhood, Sharpay and Tiara discover that Gabriella has a chance to go to college early to Stanford. Sharpay later convinces Troy that he is the only thing keeping Gabriella from her dream. Troy talks to Gabriella about this over pizza, and after sharing an awkward goodnight, Gabriella sings and leaves for college the next day.
