Past tense: Stills: the past 1944, in the vast sea, a cargo ship full of Chinese prisoners of war and labor bound for Japan. Among these Chinese prisoners and laborers are the Kuomintang army prisoners of war led by Zhou Shang Wen (Duan Yihong), the Eighth Route Army prisoners of war led by Xiao Hansheng (Bae Soo-bin), and the Liu Jia Zheng (Wang Weiguang) Ordinary labor. These prisoners of war and labor unknowingly were taken to a small island in Japan called Kuzujin Island. On the island of Kumazu, the Japanese army carried out a very confidential military defense operation in preparation for the decisive battle that might occur in Japan. In order to build this military fortification, many Chinese prisoners of war and labor are forcibly subjected to heavy manual labor every day, starving and suffering from the humiliation of Japanese soldiers. If you want to escape, the only way is to be cruel to kill. In such cruel and inhuman conditions, prisoners of war and labor are still looking forward to returning home. Gang Tian (Koji Yano), head of labor camp, once assured POWs and laborers that this is a tremendous warehouse and will send you home if you finish it on schedule. Zhou ShangWen analyzed the current situation, that the best way is to follow the requirements of Gang Tian, as soon as possible to complete the construction. Being able to return to his native country alive is the greatest wish of Zhou Shang Wen. Therefore, he warned his men not to rebel against the Japanese, to work hard and to return home as soon as possible. Xiao Hansheng and Xia Ming Yuan (formerly Guangjie Li), a KMT spy agent, soon realized that the project was an important military defense for the Japanese army. In order to stop the construction of this project, they constantly secretly organize their own subordinates, trying every means to undermine the construction and find the opportunity to run away. The different ideas give rise to a hostile mood on both sides. Once, the Japanese discovered that the working tools were destroyed, and all workers would be punished for this purpose. Xiao Hansheng stood up and was hung in a cage by Japanese people and tortured. Xiao Hansheng's brave action touched all the workers. Their national consciousness began to sprout and decided to stay together closely. In order to prepare the insurrection, Xiao Hansheng set up a five-person secret organization "Tangshan." They secretly collected explosives in their work. In order to be able to get in touch with the outside in order to tie in with their riots. They tried their best to get a Korean man named Li JiCheng (Jia Hongwei) successfully fled the labor camp and instructed him to actively prepare for the incident. Japanese authorities sent a female medic for labor camp called Miyuki Muto. Miyazaki and Gang Tian used to be lovers. Gang Tian received an order from the top army to kill all prisoners of war and labor after the project was completed. Xiao Hansheng and others meeting in the confines of the tunnels, and Liu JiaZheng, who had been secretly observing them, were captured by the Japanese. Liu JiaZheng fought the Japanese with a courageous spirit of an ordinary Chinese and was brutally murdered by the Japanese. Zhou Shang Wen, who is in very weak condition due to serious illness, bet against chess with Gang Tian, forcing Gang Tian to release prisoners in custody. Unfortunately, fainted. He knew in his heart that he would soon die. Inadvertently, Xiao Hansheng found that Shan HongShi (Xinyi Peng ornaments) is a girl.She silently protected her in this brutal, starving man's labor camp. Gradually between the two initiation of love, the two agreed with each other: If you can live back to China, Hongsheng will be the bride Xiao Hansheng married. Li Ji Cheng, who escaped, was helped by a North Korean girl named Shun-Ji (SongTianYi) and rehabilitated at the Shun Ji home. He made the final preparations to meet the escape of labor camps. Unexpectedly, it was discovered by the Japanese soldiers that they were killed in the bayonet. The project is coming to a close and the labor camp carried out a dying riot. During the riots, the prisoners and laborers bravely resisted and fought side by side and marched hopefully toward the fishing boats that were anchored at the seashore. However, when they reached the sea, the fishing boats were washed out of heavily armed Japanese soldiers, a fierce gunfire, the beach was stained with blood, prisoners and laborers covered the body of the beach. Xiao Hansheng rushed to the cliff, with blood covered with determined to jumped into the sea. Now: Stills: Now in 2002 in Beijing, the Japanese girl Qing ShanXiaoBaiHe (Sayuri Oyamada), a filmed documentary, met Xiao Hsiao's grandson Xiao Yi (Tsuyoshi Abe) occasionally. In an interview with the elderly in China, Xiaobali heard Xiao Hsiao-sheng's real story about what happened at Kuratsu Island and she was very much interested. Xiao Yi and Xiaoyi He are determined to go to Japan to find evidence that they have been buried, in order to fulfill Xiao Hensheng's ill-intentioned wishes. In Japan, Xiao Yi and Sayuri take the only clue that they found Li JiCheng and Shun Daughter's son Shan DaoCheng (Ishida Tetsuya) on Kuchingjin Island. However, he kept silent about his parents. At the same time, they found the monument to Chinese laborers Zhong Cun and his daughter, Chinese laborers, that year. The two of us are very happy to get this clue, each other's affection is constantly increasing. Sayuri's grandfather knew they were investigating the island of Kuratsu. He demanded that Sayuri Yoji brother Koizumi (Koji Yano) persuade Sayuri and Xiao Yi not to investigate the past again. Yohei, a politician who is running for the legislature, began to hinder Lily and Xiao Yi from looking for evidence, considering the political life that might affect him. Zhong Cun has died, Xiao Yi and Lily found Zhong Cun's daughter Ya Tak (Takako Kitagawa). Yaad told them that Ikeda was still alive. However, when Xiao Yi found Ikeda (Endo just ornaments), Ikeda on the past things without mentioning, so that they feel deeply from the war of this has been sealed in the past, the search for facts is a very difficult thing . From television news coverage, Xiao Yi and Sayuri found the trail of Yamahana (Matsuno Junichi). Yang Ping In order to prevent Xiao Yi and Sayuri, Xiaolizi forcibly taken away, closed at his grandfather's home in Gang Tian. Xiaoyi, who was shut by her brother at home, was very much missing Xiao Yi and finally escaped from the house and found Xiao Yi. The two hugged and listened closely to the love voice. Ikeda was touched by the sense of justice of Xiao Yi and Sayuri and asked Miyazaki Miyazaki (Keiko Keiko), who is still alive, to announce what happened to Kuratsu Island that year. But did not think this wish has not yet come true to leave the world.Miyazaki, conscientiously condemned, wrote a letter to Xiao Hansheng, in which she answered Xiao Hsiao-sheng's intentions. The petty lily's grandfather handed out a "duty diary" and told Xiaobali about the truth. Little lily can no longer face Xiao Yi. Xiao Yi, with "Duty Diary", embarked on his journey back home. The ship has left. Suddenly, Xiao Yi saw the colorful balloons and waved Sayuri. Written - "China, Beijing, Xiao Hansheng received" the letter was finally sent by the postman Xiao Hansheng's courtyard. At this point, Xiao Hansheng has been buried underground. Bright Beijing Changan street, Qing ShanXiaoBaiHe has returned to happy look, her side is an equally happy and confident boy, it is Xiao Yi.
