During the summer vacation, Xiaoyue and Xiaomei followed their father to visit their mother in the country, because their mother was ill and was resting in the country. One day, when Xiaomei was playing in the yard looking for acorns, she accidentally saw the little totoro. The little totoro wants to get rid of Xiaomei, but she leads Xiaomei to the sleeping big totoro, which makes both Xiaoyue and Xiaomei excited. One rainy night, when Xiaoyue's sisters were waiting for the bus at the station where Dad came back from work, my totoro appeared. Abortion lent it an umbrella, but it was considered a very interesting toy. My neighbor totoro gave abortion and Xiaomei acorns, which made abortion and Xiaomei very happy. Abortion they also saw my neighbor totoro, the cat bus they took.

At the end of summer, abortion and Xiaomei received a telegram from the hospital. Their mother is not feeling well, and the two sisters are very worried about her illness. Xiaomei complains that her sister doesn't care about herself, and her sister blames Xiaomei for not being sensible. Xiaomei cried and called her sister an idiot and ran away. Abortion hurriedly looked around for Xiaomei.

It was getting late, and Abortion thought of asking my neighbor totoro for help. My neighbor totoro helped Xiaoyue call a cat bus and finally found the lost Xiaomei. After that, the cat bus took the two sisters to the mother's ward window. The two sisters don't know how happy they are to see all the safe mothers in the distance. Xiaomei hurriedly gave her mother the corn she picked when she got lost, hoping that she would recover soon.
