Two children are born in the same village at the same time. One child is born as the son of the wealthy Lord Kim's family, while the other child, not even knowing who his father is, is born in a mud hut as the son of a poor woman named Maksun. However, the mother of Lord Kim's family ends up dying after giving birth to the child. To have the child breastfed, Lord Kim brings Maksun, who also gave birth on the same day.
