After 10 months of a self imposed lockdown, Francisco wants to have sex.

A disappearance brings up a couple's toxic relationship.

Between 1931 and 1993, the main Renault plant occupied the whole of an island in a loop in the river Seine to the west of Paris. This was one of the most modern factories in Europe. It was also a bastion of trade-unionism, one of the major hotspots of the events of May and June 1968. Decugis’ film records a process of dismantlement, month-by-month, from April 2004 to March 2005. Demolition began at the downstream end, with the generating plant, then proceeded building by building. The camera remains on the opposite banks, filming the island from across the river. The narration pinpoints and expounds on what is being shown. By March 2005, ‘deconstruction’ is complete. Depollution lasts into 2006.

A journey across unique places that challenge the world of their time, landmarks of the future built by revolutionary minds that can be described, each in their own way, as architectural utopias. The film is divided in five chapters which represent five works.
