Chen Mo is an ordinary person. Late on Friday night, he got on the last bus No. 375 In Beijing. Three people in dark cotton robes came into the car. They were silent and motionless, and they smelled of decadent sweetness. An old man pushed him out of the car. The next day, the car was found in Xiangshan, empty. There was no Chen Mo in the surveillance, and his message records disappeared out of thin air. He started to investigate and found that there was a similar car in 1976, and the people on the car were no longer there. He traveled across China and encountered strange stories one after another, and found that he was being forgotten by the world little by little. And those three people were getting closer to him little by little. He is not a hero, he is just a walker who cannot stop.
