Lawyer Lin Xiaoqing goes back to the countryside with her boyfriend to meet his parents, and discovers that her mother-in-law He Chunmei has been bullied by her husband's family for thirty years: her greeting gift was snatched, she was not allowed to sit at the table for meals, her stock-purchasing money was withheld, her daughter's tuition was diverted, and she was almost married off to a forty-six-year-old boss for a sixty-thousand betrothal gift. Xiaoqing reveals her identity as a lawyer to back her up, helps her mother-in-law recover one hundred seventy thousand in arrears, stops the private sale of property, forces back the marriage suitor, and finally assists in the divorce. A daughter-in-law uses a session of shielding to help a woman who has endured for thirty years take back her life.
