Joseon, 1636. A bloody political war is raging in the country, and half the population has become slaves. The slaves are making plans to join the enemy army, as they will gain equal rights and the opportunity to live a decent life under a new ruler. One day, one of the slaves belonging to the family of the young nobleman Lee Dae-gil sets fire to his master’s house and escapes with his younger sister, who was the master’s secret lover. The entire family, except for Dae-gil himself, dies in the fire. Driven by a desire for retribution after long wanderings, the young man becomes a fearless and famous hunter of runaway slaves.
