During the 60th birthday banquet of machinery factory worker Liu Zhendong, his third son Liu Xiaoyu publicly exposes years of suppressed grievances—at 19 he dropped out of school to work, using his sweat and blood money to support his eldest brother pursuing a doctorate, his second sister taking the civil service exam, and his fourth sister preparing for graduate exams, only to be repaid by his father's partiality and his family taking things for granted. When the demolition housing distribution excludes him once again, he brings out his account book to a showdown, tearing open the family's veneer of warmth. From eruption to reconciliation, it tells the story of an honest man's awakening, and also reveals the importance of communication and understanding within a family.
