Sharpay plots to get together with Troy by getting him a job at Lava Springs Country Club, which her family owns. To her chagrin, Troy brings with him all of his friends, including Gabriella. She instructs Mr. Fulton, Lava Springs' manager, to make life as miserable as possible for the rest of the Wildcats, going so far as to have him distribute a memo saying that the junior staff is not allowed in Lava Springs' Midsummer Night Talent Show, no exceptions. She also provides many opportunities for Troy, including getting him a personal training session with the University of Albuquerque Redhawks.
Sharpay's actions push everyone away from her, and she soon finds herself unable to sing anything at all in the talent show. Troy no longer wants to sing with her once he sees how her actions have made him act towards his friends, and her back-up plan, Ryan, has sold his tiki warrior costume online- at her suggestion, no less- and has no desire to sing with her either. Finally, when she is alone and crushed, Troy takes pity on her and brings her onstage for the junior staff's performance of "Everyday." She is nearly awarded the Star Dazzle Award, but it gives it to Ryan as a recognition of his hard work with the other Wildcats.
The movie ends with Sharpay having learned her lesson and friendly with the other Wildcats ... for now.
