Nagase Takashi tortured British POWs during the building of the Thai-Burma railway. He has spent his life since trying to make amends and wants the railway declared a UN World Heritage Site before he dies.

Nagase Takashi still breaks down when he remembers the young British man he helped torture. “I couldn't bear his pain,” he says, choking back tears. “He was crying Mother! Mother! And I thought: what she would feel if she could see her son like this. I still dream about it.”
