Tetsuo lives alone while working in the transportation industry. A quiet man with almost no friends, he always spends his time alone. One day, he hears a loud argument coming from the neighboring apartment. The voice belongs to Nanao, a young married woman suffering under her unemployed and abusive husband. Tetsuo feels sympathy for her situation. Later, he is invited by a coworker to visit a strip theater. Though uninterested, he goes along—and is shocked to see Nanao, his neighbor who always looked so sad, performing on stage. Her smile now is completely different from before.
