The Japanese film "The Wife of a Spy" tells about Kobe, Japan, in 1940. On the eve of the Pacific War, Yasuhiro Fukuhara (Takahashi), who was doing business in Kobe, Japan, went to Manchuria, and was surprised to see the atrocities of human experiments carried out by the Kwantung Army in Northeast China. As a pacifist, he tried to obtain confidential documents and planned to go to the United States to expose them. Youzuo originally wanted to keep a low profile, but he couldn't hide from his wife, Congzi (Sorai You). But he was not afraid of being betrayed by his wife, but was deeply afraid that such a burden would become a burden that would overwhelm her.
