In this sardonic but sobering exposé, activist filmmakers Judith Helfand and Daniel B. Gold reveal the potentially toxic effects of polyvinyl chloride (PVC), which is used in everything from cars to water mains to toys. Armed with a piece of blue vinyl siding, Helfand and Gold head to Louisiana -- America's vinyl-manufacturing capital -- and to Italy, where bigwigs from a PVC-producing company stand accused of manslaughter in a landmark case.
