Hearts Beat Loud is a lighthearted drama about Frank Fisher (Nick Offerman) and his daughter, Sam Fisher (Kiersey Clemons). Frank and Sam live in the hip Brooklyn neighborhood of Red Hook. Frank is under financial pressure to close his vintage record shop, while Sam is about to head off to college.

He decides to record a song with Sam during a “jam sesh.” Sam needs some convincing, but she agrees and their first song becomes a huge Internet hit. Frank then pushes Sam to make another song and to form a band with live performances. With their shared love of music, Frank and Sam begin their quirky musical adventure together.
