The most cruel animal is the human being.
In a future where natural disasters have provoked the worst catastrophes to humanity due to global warming, governments have created a huge natural reserve, evacuating humanity below the Tropic of Cancer. Years later, they send a spy to investigate rumors that a few humans remained in the reserve, have become primitives, survived organized in tribes and are devoid of moral scruples. Murder is a simple option. They are organized in small tribes: the SKULLS, the YELLOW EYES, the MEN-BIRD and the MEN-MADRILLO, the most feared. But the most ruthless and bloodthirsty inhabitant of the Great South is Vic, a 9 year old kid, who lives alone with old grandpa on the tree.
