As a social judge of the "Abnormal Soul Processing Section" of the underworld, Lin Chen received an outrageous KPI: to investigate his own past life in the world - an unlucky ghost trapped in a time loop who must die every day. In order to complete the task, he was forced to "punch in" and return to the world every day, possess "himself" who was about to be killed, and solve endless death mysteries within 24 hours. Car accident, falling from a building, poisoning... The ways of death are updated every day. However, in the process of saving himself, he discovered that all the conspiracies pointed to a woman he had forgotten, and an unforgettable sadomasochism full of mistakes. The countdown to saving the body is reaching zero every day, and the journey to uncover the truth about love, trauma and cycles has just begun.
