Two years after the Fukushima Daiichi meltdown, doctors and parents in the surrounding prefecture report a rise in childhood thyroid cancer cases, and this film investigates the claim that a cancer cluster has formed inside the radiation zone. It follows families living near the exclusion boundary, interviews physicians conducting mass thyroid screenings of local children, and weighs their findings against government and industry assurances that radiation levels are safe. Footage moves through evacuated towns and testing clinics, with officials and independent researchers offering sharply different readings of the same data. The film does not settle the medical dispute so much as lay out the numbers, the screening methodology, and the anxiety driving parents to demand answers. What emerges is a portrait of a population left to interpret contested science about their own children's health, with the Fukushima disaster's long-term consequences still unresolved years after the initial evacuation.
