It's snowing in the capital for the first time, and bone photographer Xie Tingzhou receives an unlit bone lantern.
The lamp owner is himself, and his death date is tomorrow.
The bone lamp can illuminate the deceased's strongest seven-minute obsession before death, but every time Xie Tingzhou lights the lamp, he loses a piece of his memory.
He saw in the lamp that the cold-blooded death row prisoner Pei Zhaoye put the knife into his heart with his own hands. But Pei Zhao will be killed at night and day, and he will never survive until the predicted time.
Xie Tingzhou was imprisoned overnight. Across the cell door, the man he had never seen before called out his nickname that had been forgotten by the world.
"A Zhou, why did you forget me again?"
One who keeps forgetting, one who is forced to remember the lives of countless dead people. The two were forced to go together to investigate the "Living Bone Lamp", but gradually discovered that the peace of the entire dynasty was actually purchased with the names and memories of tens of millions of people.
Later, Xie Tingzhou forgot his hometown, his old hatred, and Pei Zhaoye.
Pei Zhaoye just put the lamp back in his hand: "You don't have to think of me. Just choose again."
A lamp shines on the bones, and one person spends the long night. Some people want the world to forget suffering, but they want to leave names for the unknown.
