Our story begins on an overpopulated planet, with limited resources but a striking technology. In this world, the authorities designed a perfect and inclusive garbage recycling system, allowing a limitless reuse of the resources. We find our hero, Clodomir, at the collection center, throwing his household waste away. Without knowing why, he passes out and falls head first into the collection hole. He will wake up on a gigantic garbage pile, in the middle of a cave, miles underground. Then, his sole purpose will be: to go back to the surface.
