Opioid overdoses have become the leading cause of death among Americans under 50, and this film traces how a synthetic painkiller meant for surgical patients turned into the drug driving that statistic. It follows the route from pharmaceutical prescription pads to street dealers, showing how fentanyl's potency, a dose measured in micrograms rather than milligrams, makes it cheap to traffic and easy to overdose on. Interviews with users, families of the dead, first responders, and law enforcement fill in the human cost, while the film maps how the drug moves through supply chains into communities that had never seen an opioid crisis before. Scenes from emergency rooms and needle-exchange sites make the scale concrete rather than abstract. The film treats addiction as a public health emergency rather than a moral failing, and spends real time on what first responders and treatment programs are up against as the drug spreads into new regions. It closes without a tidy resolution, because the epidemic it documents hasn't ended.
