Lu Lin stood at the scene of the murder, holding a bloody knife in his hand, but the reflection in the mirror was another version of himself - Shen Yao. The rain didn't stop that night. His fingerprints were hidden in the evidence bag, but he was nowhere to be seen on the surveillance camera. He personally solved the serial murder case three years ago, and now every corpse is a replica of the scene in his dream. When Shen Yao walked out of the police archives room, he handed over a transcript with a smile: "Officer Lu, did you kill yourself or me?" The truth was torn apart in the closed loop of time, two men, one identity, and an unclaimed death. Who is the real murderer? Who is being judged on his behalf?
