An elderly rural couple wins ten million, but tells no one, only claiming the old man is sick and going to the city for medical care. Their eldest son, who has a house and a car, rents a rundown house overnight to fake poverty, eating pickles and thin porridge every day, just hoping his parents will leave soon. The younger son, squeezed into a top-floor rental room, gives his only bed to his parents, sneaking out at night to carry heavy loads to scrape together medical expenses. A month later, the elderly couple returns to the village to divide the family property. The eldest son's family rushes back in grand style, acting more and more vigorously, until the village chief reads out the lottery amount in public. It turns out this family division is a scale that weighs human hearts.
