Hardy Vallejos earns his living selling all kinds of cheap things in the midst of the yellow chaos of buses in Santiago de Chile, in 2005. After the government announces the intention to prohibit this activity in order to transform the city’s image, Hardy and his colleagues organize the biggest active union of Santiago. More than two thousand workers will unite to keep their place in the new transportation system and will soon realize that the only way to make themselves be heard is by adding to their trade the tools of modernity: wear a uniform, create a corporate image and learn how to sell their union demands in a moving and convincing way. A unique story of collective professional consciousness rising and, at the same time, a full-of-humour portrait of the Chilean city and its citizens.
