When Kousuke travels to Tokyo for his university exams, he moves into his Aunt home for a week. To his shock, he discovers that his once-elegant aunt has become a slovenly woman living in a house overwhelmed by hoarding and filth. Despite the nearly hobo-like conditions of her "trash room," Ai remains an incredibly seductive woman with an impressive bust and a hidden, uninhibited desire. Trapped together in the suffocating atmosphere of the cluttered house, a raw physical obsession ignites between them. For seven days, far from the eyes of the world, they engage in a cycle of relentless encounters where the aunt's lazy personality and overwhelming curves lead to a messy, forbidden affair.
