In 1957, in a cramped four-and-a-half tatami mat room, a widow named Maki indulges in lustful desires while reminiscing about her deceased husband. As her husband's forty-ninth day memorial service comes to an end, various visitors begin to appear at her doorstep. Trapped within the confined space of her tiny room, she becomes ensnared in an inescapable curse. A sensual, haunting banquet of passion and hatred unfolds, where desire and resentment intertwine. Amidst the poverty of that era lies a unique richness—an extraordinary, deeply melancholic eroticism born from the limitations of her four-and-a-half mat world.
