Plot

The Naked Brothers Band begin filming a motion picture called The Top Secret Naked Brothers Band Musical Mystery Movie. Nat tries to grapple why Rosalina is trying to get herself written out of the script.

To Nat's dismay, he later discovers that Rosalina is going to leave for a 6-month boat cruise around the world for winning a violin competition and becomes mad at her. Meanwhile, Alex freaks when he finds out that he has to kiss his skateboarding buddy, Juanita (Teala Dunn), for a scene in the film.

During the time Nat is moping around, he develops feelings for his costar, the renowned actress Miranda Cosgrove, and he feels confused after kissing her for a scene in the movie. After that, Miranda suggested that Nat should do something very nice for Rosalina, before she leaves for the cruise.

Nat finally accepts that Rosalina is leaving and decides to perform a serenade for her with the band, by singing her his self-written composition, "Your Smile", outside of her apartment. In conclusion, in the subplots, Cooper becomes the new director of the movie, and Juanita did not have to kiss Alex—as it was only a typo by the screenwriter; instead Juanita only has to kick him.
