Aarón Medrano has been haunted by the onstage persona of his favourite DJ ever since his mother passed away. He seems to know all of Aarón's deepest fears, like how his brain doesn't work the way it should and that's why his brother and father seem to be pushing him away. He thinks his ticket out is a scholarship to the prestigious Acadia School of Music. That is, if he can avoid blowing his audition.

Mia Villanueva has a haunting of her own and it's the only family heirloom her parents left her: doubt. It's the reason she can't overcome her stage fright or believe that her music is worth making. Even though her trumpet teacher tells her she has a gift, she's not sure if she'll ever figure out how to use it or if she's even deserving of it in the first place.

When Aarón and Mia cross paths, Aarón sees a chance to get close to the girl he's had a crush on for years and to finally feel connected to someone since losing his mother. Mia sees a chance to hold herself accountable by making them both face their fears, and hopefully make their dreams come true. But soon they'll realize there's something much scarier than getting up on stage-falling in love with a broken heart.
