During the Anti-Japanese War, Lanzhou served as an international transportation hub connecting China and the Soviet Union, an important military town in the northwest, and the rear area. Its underground working conditions were extremely complex and crucial. All forces are competing here, and underground work is characterized by multiplicity, intersectionality, and high risk. As a strategic hub in the northwest and a key node in the Soviet Union's material channel for aiding China, Lanzhou's political status has become increasingly prominent.
"Asynchrony" is based on the secret war from the Anti-Japanese War to the early days of the founding of the People's Republic of China. It depicts the special cooperation between Ma Lan, an underground party member of the Chinese Communist Party, and Chen Qing, a code-breaking expert, which spanned ten years. Malan, code-named "Nightingale", used his extraordinary wisdom and multiple identities to deal with the enemy camp, while Chen Qing, an undercover agent code-named "Asynchronous", used secret rooms and radio waves as his companions to face the complex enemy situation in Jincheng Lanzhou. The two cooperated tacitly to overcome difficulties together, but relied on time differences to transmit intelligence, forming an "asynchronous" combat mode.
From cracking the Japanese military's secret messages to seeing through the Kuomintang's "Gecko Plan", one of them danced in front of the stage, and the other played chess behind the scenes, using unconventional communication networks to build the underground Great Wall.
When the dawn of New China arrives, this comrades-in-arms friendship established in misplaced time and space finally completes its mission on the eve of dawn. No difficulties or obstacles can stop us from moving forward!
