One day, a man visits Haley and Annie's farm. He tells them about their father's debt and asks one of the girls to marry him to pay the debt. After the girls refuse and promise to return the money, the man tells them that their father was a speleologist and shared a map of where he hid all of his treasure. Since the treasure mines are cursed, only those with his blood running in them can enter. The man asked them to collect the treasure for him and gave them one month to do so.
