Nadia Collot's investigation follows the money behind the global tobacco trade, tracing five decades of industry growth built on strategies to keep smokers hooked while public health systems absorb the cost. The film moves across three continents, from boardrooms and lobbying offices in Europe to tobacco farms and marketing campaigns in the developing world, where cigarette companies have shifted much of their growth as Western regulation tightened. Interviews with former industry insiders, public health researchers, and anti-smoking campaigners lay out how manufacturers manipulated nicotine levels, funded favorable science, and worked to delay or water down regulation for decades before internal documents forced parts of the story into the open. The France-Canada co-production treats tobacco less as a consumer product than as a case study in corporate power, showing how a single industry built political influence strong enough to outlast decades of medical evidence against it. It ends without a tidy resolution, since by its own account the industry's methods have simply adapted rather than stopped.
