Mia Kaplan lives an unassuming life tending bar at a local music dive in downtown Chicago. When an up-and-coming band takes up residency, not only does she have to play nice to every fangirl that walks in the place, she also has to deal with the cocky, yet irresistibly handsome lead singer. With her brother's growing juvenile record, her father's drunken tantrums, and the unwanted (albeit entertaining) attention of this singer who has set his sights on her, Mia has to decide if she's ready to break down her carefully built walls.
