Based on the work of ACLU of Michigan investigative reporter Curt Guyette, “Here’s To Flint” is an exhaustive probe into how the city of Flint was left exposed to lead-tainted drinking water for nearly two years. Guyette broke the story of lead contamination in the Flint water supply in July when he published an EPA memo highlighting toxic-waste levels of lead in the water flowing into one Flint residence. The ACLU hired local filmmaker Kate Levy to team up with Guyette to produce the documentary.
