Mental health professionals, historians, and former officials examine Donald Trump's behavior through the lens of the Personnel Reliability Program, the military system used to screen anyone with access to nuclear weapons for psychological stability. The film opens with that framework and asks whether a sitting president would pass it. Psychiatrists including Bandy Lee and other members of the "Duty to Warn" movement walk through patterns they see in Trump's public statements and conduct, from Twitter outbursts to rally speeches, while historians place him against past leaders whose instability had national consequences. Former officials who worked alongside him describe specific incidents from inside the administration. The film also covers the fallout from mental health professionals speaking publicly about a public figure they have not clinically examined, including the American Psychiatric Association's pushback on the long-standing "Goldwater rule." Interviews are direct and clinical rather than partisan in tone, building toward a specific question: what happens when the person with sole authority to launch nuclear weapons might not meet the standard required of a missile technician.
