Spy Codename: Jackdaw

[Double undercover | Anti-Japanese spy war | Three-party game | Suspense | Germ warfare conspiracy] In Shanghai in 1941, underground party member Lin Yan lurked under the pseudonym "No. 76" Of Wang Puppet, but was forced to assume the identity of a "chess piece" by the military commander, and was forced to work in the cracks of the underground party, military commander, and the Japanese and puppets. His core mission, the "Fox Hunting Project" - to uncover the "White Owl", a senior Japanese spy within the underground party, encountered a life-and-death disaster at the very beginning: During the mission, he accidentally shot his younger brother Lin Mo, who had been separated for five years. Before his death, the other party sent half a secret message pointing to the "White Owl", but the body disappeared mysteriously. Shen Manli, a colleague of "No. 76", Is sometimes an enemy and sometimes a friend. She is the adopted daughter of a Japanese military professor, and she also hides the secret of revenge for her fiancé. The bacterial samples of the Japanese military's "Pufferfish Project", the underground secret room of the Hudong Textile Factory, and the "Shadow Owl" at the Nanjing headquarters are all entangled with clues. When Lin Yan discovered that there was more than one "White Owl" and even implicated his father's undercover mystery and the Japanese army's larger "Black Crow Plan", he realized that this espionage chess game was already full of life-threatening traps, and every step was connected to the life and death of his family, country and relatives.
