Cori Brackett built this film out of her own struggle with symptoms she traces to aspartame, then widens it into a case against the sweetener used in thousands of diet products. Doctors, researchers, and patients describe seizures, vision loss, and neurological damage they link to the additive, while the film walks through aspartame's approval history at the FDA, including the political pressure applied during the Reagan administration to get it cleared after earlier rejections. Interviews with figures like Dr. H.J. Roberts and attorney James Turner lay out the chemistry, breaking the molecule down into its components and arguing that heat and storage make it more dangerous over time. The film also profiles consumers who say they recovered simply by cutting it out. It is openly an advocacy piece, built on personal testimony and selected research rather than a balanced survey of the science, and it names NutraSweet and the companies that manufactured and lobbied for the sweetener as the story's antagonists throughout.
