Liu Mei was kind enough to care for a patient in the hospital, but the patient's condition suddenly deteriorated, causing the patient's family to argue and retaliate against her. The hospital let Liu Mei stay home for several days to avoid the conflict. Xia Donghai was very worried about Liu Mei and his family. He asked the children to be vigilant and to guard against strangers who appeared at the front door. At the same time, they also proposed some preventive measures and emergency plans. As a result, the children were all arrogant and made a lot of jokes. When Xia Donghai felt that he was over-preventing and announced the lifting of the alarm, the patient’s family suddenly came to apologize.
刘梅在医院好心为一病人做护理，但对方病情突然恶化，使病人家属大吵大闹，还要报复她，医院让刘梅呆家里几天避避风头。夏东海很为刘梅和家人担心，他让孩子们要提高警惕，对家门口出现的陌生人要有防范之心，同时还提出一些防范措施和应急方案。结果孩子们草木皆兵，闹出许多笑话，正当夏东海觉得过度防范不当，宣布解除警报时，那位病人家属突然来了，他是来道歉的。
