On a Tokyo dump’s shantytown edge, interwoven vignettes follow residents scraping by: a boy who “drives” an imaginary trolley, a homeless father and son designing a dream house, a young woman brutalized at home, drunks, schemers, and saints of small kindnesses. Kurosawa crafts a ragged mosaic of hardship, fantasy, and flickers of grace that keep people moving forward.

Ryōko Itakura returns as the tough-as-nails government taxing agent. This time she must figure out a way to expose a fanatical religious cult lead by a corrupt sociopath.

An ageing fishing boat, Dai-go Fukuryu Maru ("Lucky Dragon No. 5") sets out from the port of Yaizu in Shizuoka Prefecture. It travels around the Pacific line fishing. While the ship is near Bikini Atoll, the ship's navigator sees a flash. All the crew come up to watch. They realize it is an atomic explosion, but take time to clear their fishing gear. A short time later, grey ash starts to fall on the ship. When the ship returns to port the sailors have been burned brown. They unload the fish, which are then transported away. They visit the local doctor and then go to Tokyo for an examination. It turns out they are all highly radioactive. Their symptoms become worse, and the contaminated fish causes a panic.
