Su-san must give a lecture in far-off Iwate, which serves as another excuse for the company president and Hama-chan to go fishing. Once there, however, Hama-chan is mistaken for the company president and Su-san for his chauffeur! But Su-san is delighted at the mix-up: he gets to go fishing with a beautiful woman working at a local inn.

Hama-chan and Michiko have a son, whom they name Koitaro. At the office, Su-san's nephew begins work at the construction company and becomes friends with Hama-chan. When the nephew runs off with the sister of Hama-chan's friend, he and Su-san go looking for the young lovers ? and fishing, of course.

On a fishing trip, Hama-chan and Su-san meet a beautiful lady and the three have a great time. Later, Su-san gets a toothache, and his dentist turns out to be the woman, whom he secretly takes fishing, lying to Hama-chan in the process. When the two men later run into one another, their friendship is threatened.

One of Hama-chan's shy pupils falls in love with the daughter of Su-san's friend, and the young lovers eventually get married. After the wedding Hama-chan and Su-san go fishing, but when Su-san slips and injures his leg, concerned company employees rush to their cabin and finally learn of their surprising friendship.

Approached by a friend about a matchmaking arrangement, Su-san goes to Hama-chan's home seeking help. Hama-chan is away on a business trip, but Michiko entertains Su-san late into the night. When he gets drunk and ends up spending the night, Hama-chan, begins to question his boss's relationship with Michiko.
