Shanghai, 1940. An isolated island surrounded by occupied territory. Neon lights and gun barrels are part of everyday life.
Lu Zheng, undercover in the Military Statistics Bureau, is cornered: his comrade Li Mingde has been sent to the hellhole of No. 76. The only radio receives a ghostly coded message every night: “Night Owl.” His only inside contact writes a cell number in iodine, and there are already eyes watching him from behind.
Forgery rings, the secrets of hospital cells, counter-surveillance posts around Qingyun Lane... The hunting squad draws its blades at the edge of the abyss, every step a wager against death.
A covert war that begins in betrayal and ends in redemption, a race for life and death.
