A mother-in-law fakes dementia to ruin her three sons' marriages. She takes turns tormenting her daughters-in-law, framing them, causing trouble, and destroying their homes, throwing several families into chaos. When it's my turn, she tries her old tricks but is easily outsmarted. In the end, she reaps what she sows, ending up abandoned by everyone in a nursing home, where she dies alone in regret. The tormented daughters-in-law escape their suffering and each begin a new, peaceful life.
