On a crowded commuter train, Asuka Kirara is molested by a pervert, her mind gradually unraveling. Blackmailed by her department chief, she's forced into the office where she's made to suppress her cries while being violated, slowly enveloped by sexual pleasure. Once a perfectionist, Asuka awakens to the ecstasy of molestation, descending step by step into becoming a degenerate woman. This film portrays her descent as her daily life spirals out of control and her pride is stripped away.
