The film deals with the preparation of the first birthday party of the “Tonga”, the large bouldering hall of Mandrio – Correggio. It is the occasion to explore and see the new climbing scenery in Emilia, the region with the fewest rocks in Italy. This is a trip through some climbing halls between Reggio Emilia and Modena to discover the new fuel that is nourishing the climbing world: the wish to share fun in good company. The spirit that animates these halls is the same that inspired the current generation of 35-40 year old people who set them up. These people do not conform to the standardisation processes that are affecting other types of sporting centres in our time.
