Ten million artisanal small-scale gold miners in 70 countries around the world. I had never heard about their existence, yet my father devoted his career trying to help them. Ten years after his death in a car accident in Bolivia, where he was working on a project to reduce mercury contamination caused by artisanal small-scale gold miners in the Amazon, I embark on a journey to understand the flip side of his numerous work trips. I discover the man my father was, through the every day lives of Bolivian miners working and dreaming to the rhythm of the international gold price.
