Mother-in-Law Is Sick

During a family check-up, hospital reports are accidentally switched between a mother-in-law and her daughter-in-law. Believing herself healthy while thinking her daughter-in-law has cancer, the mother-in-law schemes mercilessly against her. But the daughter-in-law knows the truth and, betrayed by her husband's affair, retaliates with a brilliant plan. She lures the mother-in-law into selling her home for a fake inheritance, leading her and her son into ruin and debt. Ultimately, the mother-in-law discovers her own terminal illness, while the daughter-in-law reclaims her life.
