In this fourth installment of the Tora-san series, Tora-san offers a free trip to Hawaii to his uncle and wife who took a care of him and his sister after his father’s death. But not until they arrive at the airport do they learn that their travel agent has run away with their money.  Ashamed and fearing that they will be the laughing stock of their neighbors, they decide to creep into their house after dark.  Unfortunately, a petty thief enters their house, thinking that they have left for Hawaii and although they catch the thief in the end, their troubled plan is finally revealed to all of the neighbors.  On a high note, a pretty kindergarten teacher rents a room at Toraya.
