In a turbulent era, wars raged and the country was destroyed and the family was destroyed. Zhang Lei, a young anti-Japanese warrior, lost all his relatives in a tragic battle. His home was burned down by the Japanese invaders, and his parents and sister were brutally killed. Grief mixed with anger, he vowed to avenge his family and fight for his country. As fate would have it, he received a difficult task - to escort a vital piece of intelligence behind enemy lines. Accompanying him is a mysterious female warrior, Lin Xiaoyan. She is agile and intelligent. The two supported each other on the war-torn battlefield and gradually established a deep tacit understanding. However, when Zhang Lei learned that Lin Xiaoyan was actually of mixed Chinese and Japanese descent, his heart was filled with shock and contradiction. The process of sending intelligence did not go smoothly. The two lost contact with the organization and were isolated and helpless. They had to rely on each other's strength to find organization. By chance, Zhang Lei discovered that Lin Xiaoyan's father was also in China. He actually served as a military doctor in the Japanese army and held many secrets of the Japanese army. Where should Xiaoyan go? As the story progresses, their relationship is also quietly changing. They began to understand each other's pain and struggles, and faced the trauma of war together. In the flames of war and betrayal, they gradually found the meaning of each other's existence, and also understood that the real enemy was not individuals, but the war itself.
