When Chicago playwright Wendy hires amateur filmmakers Sis & Josh to record her new play, they decide to make a documentary about Wendy and her process, helped along by interviews with collaborators from Wendy's past and present projects.

Wendy hasn't staged a play since just before the pandemic and, like the rest of the world, is still finding her footing in 2024, when her new production is set to begin a two-night run at a Chicago fringe fest. Wendy and her collaborators share how lockdown affected the theater world’s reliance on the physical presence of actors and audience alike, as well as the art they made to cope with that experience. Cut to present day, and Wendy's new play—THIS MUSIC SHOULD NOT BE—is put under the microscope via footage and press photos taken at the final tech rehearsal.

Sis & Josh haven't had a project in a while either. Amateur filmmakers who always seem to be grasping for their next idea, they haven't done anything since making a zero-budget monthly movie series in 2022, and they're excited to get their feet wet again by filming Wendy's play and making a documentary about her.

But when the projects start to unravel, the directors turn the cameras on their own films and collaborators (i.e., non-actor friends and family). As the documentary spirals into a deconstruction of the frictions and parallels of the theatrical and cinematic art forms, reality begins to blur amid mounting creative desperation, culminating in a debate over the paranoiac question: "Is a play a play, or is a movie a movie, if no one sees it?"
