Lisa Spinelli (Maggie Gyllenhaal), a kindergarten teacher from Staten Island, is struggling with feelings of dissatisfaction in her life. She is in a loving yet passionless marriage with her husband Grant (Michael Chernus), and her teenage children, Josh (Sam Jules) and Lainie (Daisy Tahan), are distant with her. Lisa attends a poetry class every week led by Simon (Gael García Bernal), but her poetry is dismissed as derivative. One of Lisa's students, Jimmy, is routinely picked up late from school by a babysitter. One day, Lisa overhears Jimmy reciting a poem he wrote while he is waiting to be picked up. Lisa reads the poem at her poetry class, where her classmates and Simon are struck by it and compliment Lisa on her talent. Lisa decides that Jimmy is a prodigy, and begins to dedicate her time to nurturing his talent.
