A pocket watch that always stops at 23:59 records the most painful memories of former special police officer Chen Mo; a strange takeout order sent to an abandoned morgue drags him into the abyss of serial murders. When the food he delivered remained in the deceased's stomach, and when his face overlapped with the murderer on the wanted poster, Chen Mo was forced to embark on the road to prove his innocence.
After joining forces with the persistent female reporter Su Yao, they discovered that the food delivery system hid a "ghost program". Genius hacker Lu Yuan uses AI to select targets and carry out revenge in the name of "justice". Every victim selected was related to dark activities such as underground organ trading and illegal experiments, and Chen Mo's special police file also appeared on the death list.
