Parkinson's disease has no cure, and it is turning up more often in farming communities than statistics would predict. This film follows that pattern into rural America, where pesticide exposure over decades of fieldwork is emerging as a suspected trigger for the tremors, rigidity, and progressive decline that define the disease. Farmers, family members, and researchers describe what the illness does to a body built for manual labor, and doctors and scientists lay out the epidemiological case connecting specific chemicals sprayed on crops to elevated Parkinson's rates among the people who worked those fields. The film treats the science as unsettled but urgent, showing real patients living with the diagnosis alongside the data suggesting their work may be the cause. It is less interested in melodrama than in tracing a plausible cause from soil to symptom, and in asking what responsibility follows if the link holds up.
