Toxic remnants from the Cold War remain in millions of gallons of highly radioactive sludge, thousands of acres of radioactive land and tens of thousands of unused hot buildings, some of which are slowly spreading deltas of contaminated ground water. Governments around the world, desperate to protect future generations, have begun imagining society 10,000 years from now in order to create warning monuments that will speak across time to mark waste repositories. Filmed in Fukushima, in weapons plants, and in a deep underground burial site, the film is part graphic novel and part observational essay, weaving between an uneasy present and an imaginative, troubled distant future, exploring the struggle to keep waste confined over millennia.
