Hiding in the Walls, a new documentary from Baltimore natives Angel King Wilson and David Sebastiao, takes a deep dive into Baltimore’s history of environmental racism, specifically shining a light on lead poisoning in the city. The film discusses the origins of lead poisoning, the failures of local leadership to stop the problem, and ultimately how it came to be an uncontrolled epidemic in the city. We also hear stories from people who were diagnosed with lead poisoning as children and how they have lived with the disease, its effects, and the social stigma associated with it.
