1969年·喜剧片·寅次郎的故事2：我爱我阿妈

Injiro returned to his hometown, Chai Yo, because his sister Yingzi gave birth to a child, and met the teacher who taught him English in business school 20 years ago. Injiro's visit to Pingnei's home is ostensibly to talk old with the teacher, but in fact, it is for Xia Zi, the younger sister with a bright and orchid heart. The rich reception banquet caused the abdominal colic of Yin Jilang, who was accustomed to eating light food. Xia Zi sent him to the hospital, but Yinjiro was just a little better, so he played a game with other patients, and finally was caught in the police station. Injiro learned that her biological mother, whom she had never met, was still in Kyoto, so she began a journey to find her family. Unexpectedly, when she met the latter, she found that she had run a pornographic hotel. When Injiro returned to Chaiya, he unexpectedly caught up with the funeral ceremony in the flat. The blow hit him one after another: Xia Zi is going to marry a young doctor, Fujimura. The heartbroken Injiro had to go on the journey in silence.
