Underground there are no seasons, neither days or nights. Neon lights, low ceilings and always a bad smell. Going underground Milan opens to unusual atmospheres and feelings, while the upper city is a changing being, growing higher and higher, pushing towards the sky. Sotterranea is the exploration of this subterranean world, searching for a misterious creature and for hidden treasures, the narration of places and people forming the bowels of Milan.
