When the youngest son of a rural Midwestern family is diagnosed with epilepsy just as their insurance is set to run out, his mother dedicates her life to the illness and all of its potential treatments. Eventually she comes across the ketogenic diet, a method of limiting carbohydrates and protein in a way that some believe decreases the chance of seizures. The diet is controversial, however, and their local doctor strongly advises against employing it. Despite this advice, the child is taken to a Baltimore facility in order to proceed with the experimental treatment. First Do No Harm is based on a true story, and stars Meryl Streep, Fred Ward, Seth Adkins, Tom Butler, and Allison Janney.
