In 1935, Zhou Ke, a graduate student in the Department of Modern History, traveled to Shanghai in the Republic of China and was involved in the treacherous sea of espionage, starting a ten-year lurking career.
He has multiple identities such as underground party traffic officer, military commander's confidential secretary, and Japanese cultural consultant. He walks among the three parties of the Japanese puppets, military commanders, and underground parties. He uses the book list as a password and forbearance as a shield to deliver information and protect the glimmer of light on the tip of the knife. The tragic artillery fire in Songhu, the blood of No. 76 Demon Cave, and the sorrow of the sacrifice of his comrades have never erased his original intention; the entrustment of his guide, the wordless farewell of his confidant, and the trust of life and death have become his strength to move forward in the darkness.
From the hibernation in Shanghai to the break of dawn, from the fall of the isolated island to the surrender of the Japanese invaders, he searched for himself among multiple identities and held on to his faith at the edge of the bottom line of human nature. In the ten years of being alone, he never stood in the light, but with his lonely courage, he earned the dawn for the nation. He used his youth and blood to write the sincerity and glory of an unknown spy.
