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.

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.
