Ally Dawson (Laura Marano), a shy songwriter, works at Sonic Boom, a music store owned by her father, Lester (Andy Milder) located at the Mall of Miami. Austin Moon (Ross Lynch), an aspiring singer, interrupts Ally while she's in her practice room, singing a rough cut of "Double Take". Unbeknownst to Ally, Austin and his best friend Dez (Calum Worthy) "borrow" the song, create a video and post it on the Internet, after which it and Austin become a local sensation. After performing the song on "The Helen Show", Helen (Mim Drew) suggests that Austin return and perform another original song. Austin isn't good at songwriting, and the only solution he can think of is to plead Ally to write another song for him. Ally initially denies in anger, but later agrees to help him. The two bond while working on their next song, "Break Down The Walls", and Austin asks Ally to be there when he performs it. However, when the pianist gets sick, Ally has to fill in. This was all part of Austin's plan to help Ally overcome her stage fright, but it only ends in disaster. However, Austin and Ally become partners, along with Dez as video director, and Ally's best friend, Trish (Raini Rodriguez) as Austin's manager.
