Before her marriage, Su Li bought a spacious, single-level apartment overlooking the river with her own money, paying the full price upfront. On Lunar New Year's Eve, after spending the entire day preparing sixteen elaborate dishes, she is confronted by her mother-in-law and sister-in-law, who invoke the old Chen family rules and demand an entrance fee before allowing her to sit down and eat. Heartbroken, Su Li refuses to give in any longer. With a single phone call, she has the household's main water valve shut off and begins fighting back step by step. She gathers audio evidence, files for divorce, and exposes her husband's affair and her in-laws' schemes to transfer assets. The family plots every possible way to seize her property, unaware that the apartment belongs solely to Su Li. After a farcical Lunar New Year's Eve, her greedy in-laws ultimately suffer the consequences of their own schemes, ending up disgraced and destitute.
