Purim, the tunnels of memory (71 mn)

Twenty six people lived together for a year in Dumont D’Urville in Terre Adelie. A full year cycle, from summer to winter, in the cold antarctic continent, lived with overwinterers of the 55th French polar mission, with complete autonomy. All these they endured to ensure scientific programs and sustainability of the permanent base, in a sumptous environment.

It focuses on global political turmoil in the 1960s and '70s, particularly the rise of the New Left in France and the development of socialist movements in Latin America. Using the image of Lewis Carroll's Cheshire Cat, the film's title evokes a dissonance between the promise of a global socialist revolution (the grin) with its actual nonexistence.
