At the New Year's Eve family dinner, nine red envelopes are handed out, but Gu Niantang is the only one who receives nothing, simply because her surname isn't Xu. She cancels the elderly care package for her maternal grandmother that she had been paying for out of her own pocket, prompting her grandmother, uncle, and aunt to show up at her door and cause a scene. They twist the facts and edit a video to misrepresent what happened, even taking their harassment to Gu Niantang's workplace. No longer willing to keep giving in, the mother and daughter begin sorting out years of financial transactions, investigating the assets left behind by her maternal grandfather, and bravely standing up for their rights against emotional blackmail disguised as family affection. In the end, they establish clear boundaries and responsibilities, stand firm in their principles, and choose to enjoy a New Year on their own terms.
