Boll, a German scientist who was the star of the Manhattan Project, is lecturing at a New York university on the 50th anniversary of the dropping of the atomic bomb on Japan．The speech has become part of his summer routine(例行事务), self-justifying what was done near the end of World War II．The scientific triumph of his work, in fact, has been disturbing his life, silently troubling his moral beliefs．He has been overcome with scenes of the ruin of the Japanese city, Hiroshima．'Dreams have become nightmares,' he admits．Then his wife, an Austrian Jew whose parents were sufferers of the Nazi death camps, designs a curing journey for her husband, ringing together Boll and Amai, a woman from Hiroshima who lost her face in the world's first atomic explosion.Following his speech, Amai, wearing a face rebuilt by the skilled hands of an American doctor, makes her way to Boll．Now 56 and a documentary(纪录片)filmmaker, she wants to interview him about his role in the bomb．Boll looks to Amai to recover himself after reconsidering what he has done．And when Amai sees through Boll's face to his inner miserable state, she recognizes a shadowy reflection of the despair and tiredness that overcome the Japanese after the war, and begins to figure out the price he has paid for victory.
