Hardy Vallejos makes his living selling all kinds of cheap objects during the yellow buses chaos in Santiago de Chile, 2005. As the government announces the intention to ban this activity in order to change the image of the city, Hardy and his colleagues create the biggest active Union in Santiago. More than two thousand workers will join to keep their positions in the new transportation system and will soon realize that the only way to be heard is incorporating modernity weapons to their skill:  wear a uniform, create a corporative image and learn how to sell their Union demands in an emotional and convincing way. A unique story of collective professional awareness and, at the same time, a portrait filled with humour of the Chilean city and its inhabitants.
