In October 1947, the second year of the first government of Juan Domingo Perón, in a place called La Bomba, in northern Argentina, hundreds of people belonging to the Pilagá people were murdered.

More than sixty years after the massacre, the survivors reveal details of what happened in a documentary that demanded its director more than three years of investigation in the province of Formosa and in official files.
