Rewind at Three O'clock: Misplaced Murder

There are strange time and space rules hidden in the old city. Every day at three o'clock in the afternoon, it is forced to rewind to the early morning. The obsessive behavior before three o'clock will leave traces, but it will be misplaced on the people associated with the obsession. Criminal investigation police officer Lin Shen took over the secret room murder case of researcher Chen Yan. The fingerprints of the murder weapon pointed directly at his assistant Su Qiao, but she had a perfect alibi. As Lin Shen's experience rewinds, the traces of the murder point to him one after another, and he is forced to change from a police officer to a suspect. On the same day of the infinite loop, he teamed up with Su Qiao and others to uncover the secrets of the experiment ten years ago, and discovered that there was no real culprit in this secret room case, only traces of suicide to close the loop. But when he destroyed the core and stopped rewinding, the strange traces of time and space reappeared.
