Lone Battle: Lost City

Adapted from Dai Jin’s original screenplay, Lost in the Shadows, with the novel adaptation written by Hong Yao. Produced by iQIYI and Straw Bear Pictures, starring Huang Jingyu and Xin Zhilei.

In 1945, as the War of Resistance against Japan neared its end, the Japanese military secretly transported large quantities of poison gas bombs into China. Ouyang Xiaoan, an ace military intelligence agent, was injured while risking his life to escape the poison gas research facility “810.” He was unexpectedly rescued by Tan Moqing, who was also an agent.

When Ouyang Xiaoan woke up, he discovered that he had lost nearly four years of memories. Unable to confirm his own identity, he was left to wander alone.

Tan Moqing offered him a hand, and together they exposed the Japanese military’s conspiracy and tore away the Japanese spies’ masks. At last, Ouyang Xiaoan confirmed who he was.

But an even greater crisis awaited them. The whereabouts of the “810” files were unknown, and the location of the hidden poison gas bombs was impossible to confirm. Faced with one obstacle after another, how would this group of courageous, solitary fighters face the battle ahead?
