A military agent encounters an iron-blooded rose, and a battle between love and justice is about to begin... This is the masterpiece of Hai Fei, the screenwriter of the hit spy drama "Sparrow" and the novel of the same name of the hit TV series "Codename Thirteen Hairpins". "Code Named Thirteen Hairpins" is adapted from the hit drama "Code Named Thirteen Hairpins" co-starring Han Xue, Li Chao, Zhang Guangbei, and Xu Baihui. It tells the story of the early days of the Anti-Japanese War, when the top brass of the military command appointed Gu Xuefeng as the new head of the Shanghai Station of the military command and went to Shanghai to form a women's squad code-named "Thirteen Chai" to complete the anti-Japanese anti-rape mission. Because of their courage, superior ability, and passionate patriotism, they were spotted by Guo Chunguang, an underground member of the Communist Party of China, who eventually recruited them into the anti-Japanese ranks of the Communist Party of China.
