In the heart of a Tokyo suburb, a once-familiar neighborhood is now the setting of a bizarre and chaotic living situation — a garbage-strewn home, overflowing with trash, bad smells, and strange occurrences. The owner of this messy domain is a man who recently moved into an apartment after starting a new school program, only to find himself in a situation far from what he expected. The apartment, described as a "garbage house," is filled with discarded items, and the man is often seen picking through nearby trash bags, trying to make sense of the mess around him. He's been told by his mother — who is frequently mentioned — that this was a place recommended by the prep school, but things have only gotten worse since she passed away a few years ago.
The neighborhood has been suffering from this mess for some time now. Residents complain about the stench, the overflowing trash, and even the sudden appearance of rats. The man, once used to living with his mother, now finds himself alone in this strange environment, struggling to adjust to his new life. He’s been told by someone at the prep school that things will get better soon, but for now, he’s left to deal with the mess on his own.
As the days go by, the situation becomes even more chaotic. The man is often seen shouting at the mess, trying to clean it up, and even calling out to his mother in the middle of the night, as if she were still there to help him. But soon, another presence enters the scene — a new neighbor who moves in just as the man is struggling to cope with the mess. The two seem to have a complicated relationship, filled with tension, frustration, and eventually, a strange kind of connection that leads to a dramatic and emotional climax.
As the summer comes to an end, the local government finally steps in, preparing to clean up the mess once and for all. But before that happens, the man and his new neighbor are left to face the full extent of their situation — and what comes next is both chaotic and unforgettable.
