Nat and Alex are going to their middle school party. The theme is superhero costumes. When Jesse introduces her two sisters, Tessy and Bessy, to Nat and Alex, she tells Nat that Rosalina's high school prom is on the same day as the middle school party. Rosalina goes with the most popular guy in school because Nat tells her to (he was told it was every girl's dream). Nat gets stuck in a situation where he takes "the most popular" girl in the freshmen class, Patrice, to the prom. In the end, Patrice and Wade (the most popular guy in Amigos High School) are together while Nat and Rosalina are also together because their dates left them. They dance for a while and then leave the high school prom to go to the Masquerade Party in the middle school to perform Nat's song "I Don't Want To Go To School".
