The great adventure of the origins of the human being through the story of one and the same family, a group of men, women and children whose camera shares the trials, dramas and joys throughout major stages of evolution. Kings of the canopy, the great apes gradually left the forest until they ventured into the savannah, gradually inventing techniques essential to their survival, some of which are still in use today. Thanks to digital make-up and post-animation techniques, computer-generated images and scanner effects, life in this very distant era has been reconstituted.
