This investigative documentary uncovers the alarming global mobility of synthetic toxins in an era of high-speed international commerce. Despite increased trade, safety standards and import inspection procedures are full of loopholes, resulting in the widespread circulation of goods contaminated with dangerous substances. The film traces hazardous material violations from suppliers to storefronts—following textile producers in India, German retail outlets, and the ports and depots in between. Through interviews with activists, government authorities, and workers, The Toxins Return exposes the dangers and human costs of the unchecked spread of industrial residues and waste.
