This is a collective film shot on film, made with and by the opponents of the Cigéo project in Bure and the surrounding area, in the Meuse and Haute-Marne departments. In the film, several worlds clash, intersect, observe each other, mingle, or avoid one another. There are people who live underground, others on the surface or in the trees. We imagined what would happen in a world contaminated by nuclear power. A dystopian film? Perhaps. But also an archival film where some of the places that appear on screen no longer exist. This film was made in parallel with the struggle, alongside it, in close contact with it, in the slow, deliberate process of collective creation, between 2016 and 2020. The story was entirely written, inspired by what was happening here. It is permeated by our fears about the future, our anger and our hope that there will always be people to inhabit the threatened areas and fight against these morbid projects.
