Vashon Film Society will present “Zona Intangible,” a new documentary about Peruvian refugees made by Seattle filmmakers Ann Hedreen and Rustin Thompson, at 8:30 p.m. Thursday and 4 p.m. Friday.

The feature-length documentary, selected by the 2016 Social Justice Film Festival and the Seattle Latino Film Festival, reveals how a single act of generosity can generate change by improving health and well-being in a community founded on nothing but resilience and hope.

Award-winning writer-director Hedreen traces the unlikely connection between the people of the refugee settlement and her great uncle, a Swedish-American pioneer of the Peruvian fishing industry. Refugees fleeing the Shining Path terrorists built a new city called Manchay on the edge of Lima, Peru. A gift from an American family funded construction of the city’s first modern health clinic, inspiring other donors to send medical supplies. Against great odds, the clinic has thrived for 13 years.

With an estimated one-sixth of the world’s population now living in settlements like Manchay, “Zona Intangible” addresses challenges faced by refugees and looks at complex ties between their future and unknown benefactors.
