Tora-san returns to his family's home to attend an elementary school class reunion. After he embarrasses himself by getting drunk and insulting all his ex-classmates, he resumes his travels. In Kyushu he meets an outspoken 18-year-old girl who becomes enamored of Tora-san and follows him around. One of Tora-san's old friends is terminally ill and makes Tora-san promise him to marry his wife once he is gone.

After Torajiro's latest attempt to find a bride goes awry, he starts traveling again and runs into Utako (last seen in Tora-san's Dear Old Home), now a widow.

While Sakura and Hiroshi struggle to save funds to build a house, Torajiro befriends three young women on vacation during his travels.
