Ricky decide audicionar para el musical de otoño de East High, "High School Musical", en un esfuerzo por reavivar su relación con su ex novia Nini.

"Perder" su teléfono y perderse un ensayo importante, Nini sospecha quién es responsable de su combate con mala suerte y sorprendentemente toma represalias. EJ se enfrenta a Ricky por un sincero mensaje de voz que le dejó a Nini. Mientras tanto, el Sr. Mazzara sospecha del pasado de la señorita Jenn.

After Nini discovers that E.J. isn’t who she thinks he is, Ashlyn gets caught in the middle. Gina and E.J. team up as “wonderstudies,” and Ricky gets an unexpected visitor at home.

Miss Jenn organizes a girl’s night out with Kourtney and Nini to help Nini shake off the boy drama, while the rest of the theater kids attend the East High Homecoming dance, where Carlos learns to dance like everyone’s watching.

When Miss Jenn is placed on temporary leave and rehearsals are put on hold, the students rally together to defend their drama teacher.

A rambunctious Thanksgiving "cast party" at Ashlyn's ends with surprising news for Gina, while Miss Jenn and Mr. Mazzara accidentally spend the holiday together at East High.

When the cast and crew unexpectedly need to find a new location to "tech" their production, Carlos secures a spooky theater downtown, forcing Miss Jenn to confront old demons.

After months of rehearsals, the theater kids gear up for an unforgettable opening night. But when unexpected audience members show up to shake the cast to its core, will the show "go on" if the Wildcats aren't all in this together?

It's Act Two of opening night, and the stakes have never been higher. After last-minute cast changes in Act One — and so much left unsaid between Ricky and Nini — there's more drama offstage than on
