In 1976, a chemical explosion at a research facility near Seveso, Italy, releases a cloud of toxic dioxin across the surrounding region. Families wake to find their world transformed overnight into a landscape of contamination and fear. Children play in poisoned soil. Livestock sicken and die. The invisible threat settles into homes, into bodies, into the very fabric of daily life. As authorities scramble to understand what happened and contain the disaster, ordinary people face impossible choices. Do they stay in their homes or abandon everything? Do they trust official reassurances or their own instincts about what's safe? Parents struggle to protect their children from something they cannot see or fully comprehend. Scientists work against the clock to map the danger. The film captures how a single moment of industrial failure can fracture a community, turning neighbors into refugees in their own land. It's a story about vulnerability, resilience, and the weight of living with uncertainty when safety becomes something you can no longer assume.
