Álvaro Norte, a celebrated composer and cellist, invites his talented student Mauro to be his assistant. However, Mauro reveals he has other plans that would separate them. In response, Álvaro confines Mauro in a room, using his pain as inspiration for a new cello composition. Despite Mauro's resistance, he inadvertently ends up fulfilling Álvaro's artistic vision.
Unfortunately the movie The Composer is not yet available on HBO Max.
