A psychotic old man, living in a garbage dump, resorts to animal and human sacrifices, to control an "imaginary" demonic being living below the mountains of waste.
In the outskirts of Mexico City, people live in poverty and desolation. The lucky ones fight every day to obtain money and food, working in the most unimaginable places. The less fortunate, simply die in oblivion.... A monstrous, bleak place fills the landscape of this area: the garbage dump. Every day, workers of the Sanitary and Health Commission deliver tons of waste. There, a lonely old man, "the garbage man," spends his daily existence "operating" and looking after the enormous place. The psychotic old bloke, surrounded by rot and pestilence, has started to slaughter animals to control the hunger of an imaginary demonic being, living below the mountains of waste. Soon, animals will not be enough, and the garbage man will resort to human sacrifices instead, in his obsessive attempt to control the viciousness of the "demon". But... what if this eerie being is real?
