Man Seok is an executioner from the butcher caste and therefore discriminated against. One day, he receives a request from a noble family that one of their condemned be executed without his head being cut off. Man Seok does as instructed, but when his payment is delivered by Sook Yeong, the daughter of the executed, he rapes her, motivated by his deep resentment against the ruling elite. Later, she is arrested and sold into slavery. Feeling guilty, Man Seok buys her freedom, and the two eventually fall in love and settle down to a peaceful married life. However, their happiness is threatened when they are involved in a conspiracy against the enemies of Sook Yeong's family.
