An old man lives in a town that has become submerged in water. As the water rises, he's forced to build additional levels onto his home with bricks in order to stay above water. One day the old man accidentally drops his favorite pipe into the lower levels of his home, and decides to rent scuba diving equipment in order to go searching for his pipe. As he descends through his sunken home, the old man recalls memories of the past in each room.

Noriyasu seems like an average third-grader, but his life goes haywire after he catches his mother reading his private daily journal. In an effort to astonish her, he begins writing outlandish lies about a giant snake in the bathroom, cooking pencils for dinner, and a rain of pigs, but Noriyasu is the one who's shocked when his writings play out in reality and everyone else treats the events as normal. Things become even more chaotic when he takes several stabs at being a newspaperman, producing “fake news” that become the talk of the town and one resulting in an apocalyptic porcine holiday.
