Single mom Flora (Eve Hewson) is at a loss about what to do with her rebellious teenage son, Max (Orén Kinlan). Encouraged by the police to find Max a hobby, Flora tries to occupy him with a beat-up acoustic guitar. With the help of a washed-up LA musician (Joseph Gordon-Levitt), Flora and Max discover the transformative power of music. From the musical mind of John Carney, "Flora and Son" explores the bond between a mother and son on a journey toward a new harmony.
