The Twist/Reveal: The central mystery of the film is 'Nevers.' Through the Japanese man's gentle prodding, the woman reveals that during the war, she fell in love with a German soldier occupying her town. On the day of liberation, he was shot by a sniper. She was traumatized, and as punishment for sleeping with the enemy, her head was shaved, and she was locked in a cellar by her parents, where she went mad, clawing at the walls and tasting the saltpeter. She was eventually released and sent to Paris on a bicycle, never to return.
The Ending: After spending the night wandering the city and confessing her story, she returns to her hotel. The Japanese man follows her. She yells that she will forget him, just as she forgot the German. He enters the room, and they stare at each other. She says, 'Hi-ro-shi-ma. That's your name.' He accepts this and replies, 'That's my name. Yes. Your name is Nevers. Ne-vers in France.' The film cuts to black. This signifies that they have accepted their roles as carriers of their respective histories—they are no longer just lovers, but embodiments of the places that defined their scars.
