In the northeast Black Tiger town, the Japanese are conducting a top-secret military plan called the "Ding No." plan. In order to block the news, the Chinese workers collectively destroyed their work in construction. At this time in Shanghai, one just anti-Japanese anti-Japanese team "Jagged Manchurian Tiger" once again succeeded in intercepting the Japanese military transport line. One of the members, Luo ZhangHu, was a quick-witted, heroic man who always wanted to join the Communist Party of China and Zhang Wanliang of the New Fourth Army Liaison. For close friend. However, the interception by the "Northeast Tiger" caused serious consequences for the anti-Japanese activities of the Communist Party. Luo Zhang was guilty of endless guilt and petitioned to assist Zhang Wanliang in the task of assassinating Japanese weapons expert Matsui. In the assassination mission, forces from all walks of life were vying for arbitration. Luo ZhangHu met Lan XinEr, a mysterious woman with the same mission. However, since they did not act in accordance with the plan of our party, both people paid a terrible price and vowed to avenge their deaths for their mates as they lurked into Black Tiger Town in the hope of undermining the "Ding Scheme." Wang Xiaoyi, an underground party member who appears in a madman's face, and Zhang Wan-yi, a loving scientist who tolerates humiliation, should cooperate with each other in fighting under the influence of Lv Wang Yu, a warlord, and Zhang HongYu, a big smoker of local tobacco merchants. They incarnated the "Shadow Warriors" swaggering around the sinister Japanese military intelligence, chaos its military forces, undermining fortifications, and the shameless Japanese military intelligence leader Da Dao and the cruel greedy Black Tiger Town Commander Mei Jin struggled. In life-and-death afflictions, love is spiced on by spy games and spy games are weird because of love, and love and romance between two heroic and heroine families are sparked. In the end, the anti-UN organization got precious information from Luo ZhangHu and successfully blew up the "Ding No. Plan." However, due to the betrayal of the traitors, the "shadow warrior" was brutally smashed by the Japanese troops and the underground members of the Black Tiger town, including Luo Zhanghu and Lv WangYu, all sacrificed. Lan XinEr and Zhang HongYu, surviving the peril, are determined to devote a lifetime to identifying traitors who are selling revolution and lovers.
