When Madrigal’s (Maddie) older brother, Strum, goes missing from his college campus, her musical family loses its harmony. Her French mother is distraught — broken for the first time as Maddie has never seen her. Her piano playing father doesn’t even touch his instrument, and her fiery sister retreats into a rebellious funk, drinking and partying, even though she’s only 16. Maddie tries to keep everything together: focus on her oboe lessons and compulsive counting that calms her mind. But when her parents leave to look for Strum and Maddie is left with Aria, things seem hopeless.
