A voyage into the far west of Brazil leads us to a monumental structure - petrified at the centre of the savannah. Inspired by the epic construction of the city of Brasília, the film uses this history to imagine it otherwise. "I look at Brasília the way I look at Rome : Brasília began with a final simplification of ruins". Through the geological traces that lead us to this fictive monument, the film unearths a history of exploration, prophecy and myth.
