Tora-san, the näive and romantic peddler, returns once more to his home in Hokkaido where, as usual, he falls in love with a lovely young lady. The girl this time is Rinko Ueno, who has come home in an attempt to repair her relationship with her gruff veterinarian father, Junkichi 'Jun' Ueno. Tora-san gets caught up in the entanglements not only between Rinko and her father but between Dr. Ueno and Etsuko, a restauranteur with amorous plans for the ornery veterinarian.
