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.

While the Wildcats head to Salt Lake Slices to digest the excitement of opening night - and a pizza or two - Miss Jenn continues to experience tunnel vision over the Menkie Awards. Mr. Mazzara shows his softer side; Ricky reevaluates a party crasher; Gina speaks her truth; and Nini makes a life-altering call.

Ricky, Gina, and the rest of the Wildcats must make big decisions on opening night of HSM 3.

Act Two of HSM 3 Opening Night is shaken up by surprise guests and looming decisions.
