The film narrates the day-to-day existence of a filmmaker wandering through his city (Brussels) and who has a notion to follow in the footsteps of dramatist Antonin Artaud and visit the Tarahumara people of Mexico. This is a film about intimacy and friendship. Written in the first person, it places Boris and Brussels in the centre of the universe, here represented by the crazy, vertiginous, endless spiral of the biblical Tower. It is Boris's diary and self-portrait. He plays himself on screen (as do the cast of a hundred who also allowed themselves to be “babelised“).
