A group of East High students countdown to the opening night of their school’s first-ever production of “High School Musical.” Showmances blossom; friendships are tested while new ones are made; rivalries flare and lives are changed forever as these young people discover the transformative power that only a high school drama club can provide.
Flying high after the triumph of opening night, Ricky, Nini, Gina, and the Wildcats gather at Ashlyn's for a New Year's Eve party. Miss Jenn runs into the new North High rival theatre teacher – a.k.a her ex-boyfriend - and at the stroke of midnight, shocking revelations come to the surface.
Kourtney, Carlos and Big Red decide to join their friends and audition for on stage roles in "Beauty and the Beast," while Nini experiences FOMO from afar. When new competition shows up to the tryout, Gina tries to shake off some old habits.
Big Red and Ashlyn celebrate their first Valentine's Day together, amidst drama. Kourtney spars with a co-worker while Gina contends with being single. Meanwhile, Ricky and Nini's plans to surprise each other turn into a comedy of errors, leading to new revelations and a surprise song.
When a blizzard barrels down on Salt Lake City, the Wildcats are stranded at East High after hours, just as E.J. receives some bad news. As cabin fever sets in, Miss Jenn inspires Nini to make a bold choice about her future; Kourtney's coworker Howie makes a surprising move; and Gina and Carlos come to blows.
Gina and Seb rally the group to throw Carlos the music and dance-filled Quinceañero he never had. Meanwhile, Ricky accidentally oversteps in more ways than one, and Miss Jenn gets a wild idea about how to get Nini back onstage at East High.
After rival school North High releases a viral video to undermine the Wildcats, Miss Jenn hosts a weekend improv intensive to build up her kids' confidence. Meanwhile, Nini works on a new song at Salt Lake Slices, where she finds inspiration in Kourtney's approach to life.
When the Wildcats suspect that North High has stolen a key costume piece, they infiltrate their rival school and end up in a competitive dance-off. Miss Jenn goes face to face and toe to toe with Zack Roy. And an emboldened Nini takes a big risk.
