A post-apocalyptic universe. A metropolis of two societies. On the surface, a regime that isolates the individuals in elite. A whole city scraped in the underground, where survival is the only law. Up and down don’t merge. Yet the Mole will climb up to fulfil his dreams.

A young woman, alienated by her work and confronted to her surroundings, falls into a depression that leads her to live in a sewer to find her identity. In there, life is no better; reality appears in images and alegoric figures that change its form and vanishes, without letting the woman communicate with anyone. It's a film with zero dialog in witch the songs takes us through the states of emotion.
