The first part is titled, Big Dreams & Big Apples, and the second part is titled, Nanny In Miami. The episode aired to 4.8 million viewers.

Plot
Austin, Ally, Trish and Dez travel to Times Square where Austin is booked to perform on New Year's Eve. When they couldn't get through New York City's crowded streets, Jessie comes up with a plan to get them to the stage and to ultimately have Austin record one of her songs.

Big Dreams & Big Apples
Austin, Ally, Trish, and Dez take a trip to New York where Austin is set to perform for the ball drop on New Year's at Times Square. After many setbacks including a phone calling and booking the wrong area, an airplane flight setting down short of the actual destination, and a taxi ride with a lack of money causing them to get kicked out, Team Austin make it to Time's Square where they encounter Jessie and Emma, who had come to the ball drop after Emma convinced Jessie with the mention of Ryan Seacrest. Team Austin mentions their dilemma to Jessie and Emma, and through helicoptor flying skills, Jessie flies them up to the top of the building. Austin performs just in time, and everything seems to be going fine until the cast of Jessie realize that Zuri is missing. Part 1 officially ends when Zuri is revealed to be in the big, shiny ball.

Nanny in Miami
After the big Times Square Performance, Austin, Ally, Trish, and Dez find themselves without money or any place to stay. When Jessie and the Ross kids agree to let them stay, Jessie receives a chance to get Austin to record one of her songs, thus boosting her to the stardom she longs for. When giving all her songs to Austin and Ally, she accidently gives them Zuri's poem on imaginary friends too, which the friend duo mistake to be her only good song. Austin and Ally tell her that they like Zuri's poem which they think is her song, and through that, Jessie and the rest of the Ross kids head to Miami with Team Austin so that Jessie and Austin can perform Face to Face together at their local Miami mall. Many times, Jessie tries to either sabotage or change the song multiple times, including a guitar breakage, purposely getting Zuri out of the room, and at the end, causing Ally to have to create a tab for Jessie. The performance day finally arrives, and Jessie, due to guilt, admits that she didn't write the song; Zuri wrote the poem. Austin, althought surprised by this shock, still asks Jessie to sing with him, and she does. The one hour crossover special and Part 2 officially end when the Jessie cast minus Bertram get back to New York and see Bertram playing with his toy train set.

Trivia

 * Several references from previous episodes were made in this episode. One example was Dez repeatedly sticking random things in his pot of fondue which resembles his actions with the fryer in Bloggers & Butterflies. Also, when Team Austin didn't have enough money to properly pay for their taxi fare in New York and the taxi driver kicked them out near the hotel where Jessie and the Ross's live, it resembles the events of the Jessie pilot, New Nanny, New City, where Jessie got kicked out of the taxi after not having enough money.
