The gang has less than a week to teach first-time music students how to play in a band in anticipation of the A&A Music Factory's grand opening.

The gang prepares for the A&A Music Factory's first showcase and Austin wants to surprise Ally by teaching their students one of her songs.

Ally learns that the new woman her Dad is seeing also happens to be the mom of a very difficult student at the A&A Music Factory.

One of Austin & Ally’s music students is upset about spending Christmas away from her father, so the gang does everything they can to try and make her happy and realize that they’re her family too.
