Vaccine safety sits at the center of this film, told through three families who say their children were harmed by routine vaccinations. The film follows each family's account in detail, from the decision to vaccinate through the medical crises that followed and the fight to get doctors and regulators to take their claims seriously. Interspersed with these stories are interviews with physicians, researchers, and public health officials who represent the range of positions in the debate, along with historical footage tracing how vaccine policy in the United States took shape. The film gives real space to the argument that vaccines are essential and rigorously tested, then just as much space to parents convinced the system dismissed their children's injuries. It also looks at how politics, media coverage, and public opinion push vaccine policy in one direction or another, and at the difficulty of weighing individual medical risk against collective immunity. No side gets the last word; the three families' testimony is left to sit alongside the clinical data and the policy debate.
