The video depicts a large group of people participating in a march or protest along a city street. Many of the participants are holding signs and banners, with some indicating support for APROFEM, a union representing municipal workers. There is a large truck with speakers and additional banners, which appears to be a focal point of the march. People on the truck are speaking into microphones and addressing the crowd. The surrounding environment is urban, with tall buildings visible in the background under a cloudy sky. The march appears organized, with participants walking in the same direction along the street.
