Austin and Ally are just about ready to open the Austin & Ally Music Factory and the press is all up on them. But, when Trish and Dez accidentally tell the press that Austin & Ally can teach first-time music students how to play in a band in just a week, Austin & Ally are accidentally stuck to a promise they don't think they can keep. Their first batch of students consists of Ally's previous student Lily on bass, a video gamer named Max on keyboard, a baseball player named Herman on drums, and a tomboy skateboarder named Dylan on lead guitar. At first Team Austin is doubtful about the four and even hire extras to drown out their sound but once they connect to each student on a personal level, they are able to figure out the gateways into getting them to understanding the instruments and at the end of the episode, the band successfully performs, proving the worth of the Austin & Ally Music Factory.
