High in the breathtaking, majestic Andes of Peru, silent but deadly traces of mercury – remnants of long-ago silver mining – bring illness and death to a local village. Seeking retribution, the villagers mistakenly attribute the outbreak to Western doctors who work in the mountains. Two women – the fiancé of a villager killed in the accident and the wife of a doctor murdered in the riot – are brought together in this haunting yet ravishingly beautiful film about our divided yet inextricably intertwined world.
