Flint, Michigan's city government switched the municipal water supply from Lake Huron to the Flint River in 2014 as a cost-cutting measure, and within months residents were reporting rashes, hair loss, and children with elevated blood-lead levels. This film, produced by the ACLU of Michigan, follows the residents, activists, and researchers who pushed past official denials to prove the water was poisoned. It places viewers inside packed public hearings where furious parents confront officials, and lays out how the switch was meant to save the city about five million dollars while it exposed a largely African American, largely poor community to lead with no safe consumption level. The film names the emergency management decisions behind the switch and tracks the slow, reluctant admission that the water was the cause of the illnesses. It ends without a resolved timeline, since the crisis and its legal fallout were still unfolding, and treats Flint as a warning about aging infrastructure elsewhere in the country.
