Rebecca prepares for her audition at the community theatre musical revue, and Valencia is disappointed after she expects a proposal from Beth. Valencia decides to audition with Rebecca to avoid going back to New York with Beth. Josh decides to do theater tech for the revue, although this is mainly due to his wanting to spend more time with Rebecca, and after Nathaniel walks in during the audition to give Rebecca legal paperwork related to their work at the jail, the director insists that Nathaniel join the production.

After the audition, Rebecca gets a comedic song she'd always loved to her delight, but upon examining the lyrics, she is horrified to discover that the song is deeply misogynistic. She makes a few small revisions to the lyrics, but when she presents them to the director, she is insulted and told to perform the song as originally written. At the show's performance, Rebecca is reluctant to perform the original lyrics as they go against her morals, and she wishes that the audience could hear her lyrics. Nathaniel agrees and decides to walk out on stage and sing Rebecca's rewritten version, but the director demands that the curtain be closed before he is able to finish the song. Nathaniel and Rebecca are promptly fired and "banished" from the community theater by the director. Nathaniel admits to Rebecca that he really only joined the show to spend time with her, and they almost kiss - a moment Josh witnesses.
