Alex Fletcher, a washed-up former pop star from the 1980s, now ekes out a living on the nostalgia circuit, performing his old hits at various small venues. His life takes an unexpected turn when Cora Corman, a popular current pop sensation, invites him to compose and record a duet with her. However, there's a catch: he must provide the song within a few days, a daunting task since Alex has not written a song in years and lacks lyrical talent. Facing a golden opportunity to revive his career, Alex scrambles to create a hit song but struggles with writer's block and the pressure of the tight deadline.

Sophie Fisher, the substitute plant lady who tends to Alex's apartment, inadvertently becomes his collaborator when he discovers her gift for writing lyrics. Despite initial hesitations, the duo begins to work together, blending his musical skills with her flair for words. As they spend more time together, their partnership proves to be not just professionally fruitful but also personally challenging, as it stirs up feelings and unresolved issues in both. Their collaboration becomes a journey of musical creativity, personal growth, and the discovery of their true voices, both in music and in life.
