Rebellious and outcast boy, Chiwoo, has been searching for his identity and purpose all his life. But when he finally finds out about his father being a Mangnani, a mysterious executioner who carries out God's judgment, he is confronted by an Emperor and his army who are determined to obliterate all Mangnanies. A Mangnani's dance prior to
beheading a sinner determines the fate of one's afterlife - the
forgiveness from God, or eternal damnation.
Can you forgive someone by killing him? Can you love someone by cutting his head off? That's what a Mangnani does, and that's what Chiwoo has to find out.
