Unaware of whether the condition is medical or a result of karmic retribution, Tul begins to have second thoughts about his profession. But when he tries to quit, roles are reversed, and the hunter becomes the hunted. Then he meets a girl who turns his world even more upside down. Can Tul find redemption from the violence that continues to haunt him?
