Emma is beyond excited when she finds out that Austin Moon (Ross Lynch) is performing at Times Square. On New Year's Eve, Jessie takes her to see Austin and to their luck, they bump into him, and meet the rest of the gang: Ally (Laura Marano), Trish (Raini Rodriguez), and Dez (Calum Worthy). Plus, Jessie comes up with a brilliant plan on how to get Austin to perform on time. Later on, the gang shows up at their apartment, and Emma tells Jessie that if she helps them, he could record one of her songs and turn it into a big hit. When Ally reads Jessie's lyrics, she thinks they are not good, so Jessie accidentally steals Zuri's poem and takes credit for it. In the end, when Austin and Jessie are about to perform in Miami, she gives Zuri credit, and everybody is satisfied with Dez's impressive music video.
