In a future city where the rich and the poor are like a chasm, the desperate brother signed a contract - the "Perfect Hunting Contract" in exchange for his sister's sky-high medical expenses. The contract gave the wealthy a terrifying privilege: legal hunting rights. He willingly became prey. When his sister's life-saving money arrived, it was also the beginning of his countdown to escape. He grasped the only "authority" - that ridiculous knife, and escaped into the cold remains of the steel behemoth.
However, the hunters are faster and more deadly than imagined. The metal claws of the mechanical hound scratched the prelude of death, echoing in the empty ruins. Overhead, the suspended car roof slid open silently, and the elegant and cold hunter looked down with a gun, like a god teasing ants.
In 72 hours, the game of life and death begins. Can he use a short knife to split open a glimmer of hope under the encirclement of mechanical hounds and the precise muzzle of hunters? Between the blade and the claws of the mechanical beast, who will be stained with blood first? When the countdown reaches zero, will it be the rebirth of my sister, or the silent end of his life in this perfect hunting ground?
This is the ultimate battle about family love, despair and survival. In the legal hunting game of the rich, can the struggle and resistance of a lower-class young man tear apart this cold "perfection"?
