In 1935, there was an undercurrent surging in the French Concession in Shanghai.
Lin Wan, known as "Lin Banxian" in the world, appears to be the wealthy owner of Huangquan Photo Studio, and makes a living by taking photos of deceased people. In fact, he is born with yin and yang eyes, can see ghosts but is afraid of them, and relies on deception and abduction to make a living.
Shen Zhao, a cold forensic doctor who returned from studying abroad, firmly believes that science can dissect everything - including supernatural phenomena.
When a "smiling female corpse" breaks into the photo studio, and the shadow on the photo actually grins on its own, the enemies are forced to join forces to solve the mystery of the Yin and Yang worlds:
Taking "posthumous photos" of dead people actually captures the bloody memories of ghosts during their lifetimes;
A "vampire" murder occurred in the concession, and the murderer turned out to be a headless puppet from a dental clinic;
On the ghost train bound for Nanjing, the ghosts of Japanese soldiers sang "On the Songhua River" and asked for their lives...
And as the secret of an old-fashioned camera that can seal the soul is revealed, Lin Wan discovers——
He died when he was six years old.
The father who saved her is now wanted by the underworld.
And Shen Zhao's blood contains the experimental code of the Japanese "Undead Legion"...
