Chronicle of a Blood Merchant

Shortly after the Korean War, when people can barely feed themselves, Sam-kwan sells his own blood to get married to the town beauty. 11 years later he discovers that the eldest of his three sons is not his own, but of his wife's ex-boyfriend's. Sam-kwan is devastated with disappointment since the eldest has always been his favorite child, so he lashes it all out on his son. However, when the eldest suddenly gets sick and in need of an operation, Sam-kwan sells his blood again and again in order to pay the expensive hospital bills, putting his life in danger for a son who's not even of his own blood.
