Antibiotics, antidepressants, painkillers: the film asks how much anyone actually knows about the pills swallowed every day. It follows the pipeline of drug discovery, from lab testing through clinical trials, and talks to scientists about how a compound goes from bench to prescription bottle. Doctors and researchers weigh in on how the same medication can help one patient and harm another, and the film uses that variability to explain why side effects are so hard to predict. Addiction gets direct treatment, tracing how legitimate prescriptions for pain or anxiety can turn into dependency. The film also takes on the ethics of choosing when to die, using assisted dying as a case where medicine's power to control the body runs into questions no chemistry can settle. Throughout, the tone stays measured rather than alarmist, treating both the successes of modern pharmaceuticals and their controversies as part of the same story: a business and a science that most people rely on without fully understanding.
