Gu Chengchuan hands over his entire monthly salary of 32,000 yuan to the Shen family, keeping just 500 yuan for his own living expenses. Even the 200 yuan he needs to buy medicine for his father is withheld by his mother-in-law and squandered on his brother-in-law. By chance, he wins a lottery jackpot of 16 million yuan after tax. The Shen family immediately draws up a secret plan to divide the money, demanding 8 million yuan to buy a house and pay for their son's wedding. At a family banquet, they summon relatives to pressure him into giving in. But Gu Chengchuan sees through their schemes and decides to divorce. As his mother-in-law comes to cause trouble and his wife belatedly realizes her mistakes, he stands firm and keeps his winnings, determined to give his hardworking parents the security and peace they deserve.
