 The well-intentioned, kind-hearted, and somewhat awkward but always lovable Tora-san makes one of his periodic visits to his sister and her family in Tokyo. His nephew, Mitsu, is depressed because he has failed his university entrance examination, and also because Izumi, a young girl he is in love with, has transferred to a school in Saga, Kyushu. Mitsuo leaves home and finds her, but her bad-tempered uncle disapproves of her riding around with a young man from Tokyo. Tora-san gets involved in this complex interplay of relationships, and in his usual delightful and unexpected way, facilitates a satisfactory resolution.
