While Dae-su hunts for his captor, Lee Woo-jin, with a hammer in hand and fury in his heart, the film reveals that his quest is exactly what his tormentor intended. The narrative masterfully flips the script: Dae-su believes he is the hunter, but he is actually the prey in a much larger, more sadistic game.
