March 2020, Montreuil. As municipal elections take place in an unprecedented and uncertain context, a polling station prepares to open its doors. From the early morning setup to the nighttime vote count, « Polling Station » observes, in real time, the meticulous mechanics of local democracy. Presidents, poll workers, scrutineers, voters: each occupies their place in a precise, codified, almost choreographed republican ritual. The gestures are simple, repeated thousands of times across the country—verifying an identity, having a list signed, slipping a ballot into the box—and yet they constitute the beating heart of the democratic process. From the perspective of ordinary men and women, the film reveals the concrete workings of a municipal election: the official opening of the polling station, the turnout, the behind-the-scenes discussions, the vote count, and then the solemn delivery of the results to the town hall. Without explanatory commentary, « Bureau de vote » offers an immersion into the details of the French democratic machine. A film about collective action, civic responsibility, and the fragile reality of voting.
