Wang Mingzhe, a graduate student in the Department of Physics, participated in his tutor's quantum experiment and accidentally traveled to parallel time and space. He discovered that he had been missing for many days in this world, and there were suspicious blood stains in the laboratory. What will happen when they find a dismembered corpse in the corner of the laboratory, with "Don't trust another self" written in blood on the wall, and the corpse's fingerprints are exactly the same as Wang Mingzhe's? As the investigation deepened, they realized that this experiment opened a parallel time and space channel, causing multiple "Wang Mingzhe" to appear in the same world at the same time, and at least one of them was a murderer. What could be the reason? When the third living "Wang Mingzhe" appears, the three of them fall into the confusion of who is their true self. They must decide who should stay and who should disappear?
