Dueling narrators face off in a comedic docu-musical debate about the fate of one heavily polluted river. The Kalamazoo was described in the late 1960s as "having the color and consistency of a blueberry milkshake." Inside Kalamazoo, River: US, 'Nature' narrator Malcolm Drury (Eric McConnell) details the rich history of the Kalamazoo River leading up to its current status as an 80-mile long "Superfund Mega-Site" from PCB contamination, while Maxx Buccs (opera singer David Gordon) sings his commentary from the perspective of 'Industry,' leading to a Blazing Saddles-esque finale along the banks of the river itself. Stock footage, interviews, and a fake music video also contribute to this examination of humankind's impact on fresh water supplies. The movie is an exploration of both the relationship between a natural waterway and the city which took its name, and of the broader relationship between industry and nature.
