Rural mother Wu Guilan goes to the city to visit her son and finds that he has been psychologically oppressed and ordered around at will by his wife Lin Fang for a long time, completely lacking dignity. She strongly backs him up, but uncovers an even bigger conspiracy by the Lin family, who not only treat the son as an ATM, but also because their hometown is about to be demolished and relocated, mother-in-law Zhao Rumei opens her mouth wide like a lion, demanding money and jewelry. Swayed under marital coercion, the son even betrays his mother. Wu Guilan cleverly uses the demolition compensation to set a trap, exposing Lin Fang and her mother in their true colors. The other party steals a gold bracelet to frame the mother-in-law, but is exposed in public by Wu Guilan holding the evidence, forcing the mother-in-law to slap herself in the face to apologize. In the end, under his mother's protection, the son bravely gets a divorce and regains a new life.
