At 11:59 pm, Chen Mo saw his friend Zhou Ye, who had been dead for three years, on the streets of Hangzhou.
He chased across the road, and the half-cigarette that fell into the water cost him a dollar. When he looked up again, Zhou Ye had disappeared, leaving only an old bookstore that shouldn't exist and a familiar smell of food.
From that day on, cracks appeared in Chen Mo's familiar life: the door of his house opened for no reason, his mother remembered his never visited visit, a key with "1402" appeared in an old drawer, and his long-dead friend actually paid off the debt he had kept for three years.
The closer he gets to the truth, the less he can trust his own memory.
His girlfriend Lin Wan began to secretly investigate him, and his friend Zhao Kai denied the common experience. Insiders kept stopping him with reasons that were difficult to distinguish between true and false. The only thing that is certain is that the building where Chen Mo lives is only on the thirteenth floor.
But one night when he had just regained his composure, the elevator crossed the thirteenth floor and sent him to a non-existent corridor.
At the end of the corridor, the door of 1402 is slowly opening.
Someone at the door told him to go home for dinner.
What happened at 11:59 three years ago?
If the person in the photo is really Chen Mo, then who does the past that he has always regarded as his life memories belong to?
