Jack Herer spent decades arguing that hemp prohibition had nothing to do with public health and everything to do with protecting the timber, cotton, and petrochemical industries from a plant that could compete with all three. The film follows his research and activism, tracing how that work became his book The Emperor Wears No Clothes, self-published and later dubbed "the hemp bible" by the movement it helped build. Interviews and archival material lay out hemp's industrial history, from rope and paper to fuel and fiber, and the arguments Herer used to explain why a crop with those uses ended up criminalized alongside marijuana. The film sides squarely with Herer's account of a coordinated suppression campaign rather than presenting a neutral survey of drug policy, treating him as a lone crusader whose singular fight grew into an organized push to reform marijuana and hemp law in the United States. It works best as a portrait of the man and the case he built, not as an outside audit of the claims.
