[Different stories, different copies]
At 3:17 in the morning, the broadcast from the abandoned funeral home rang on time: "All employees please go to the morgue to get today's work manual." As a new "employee", Lin Mo was forced to join this weird shift game. The rules in the manual are constantly changing—yesterday it was "Don't look at yourself in the mirror," today it's "You must say goodnight to every corpse," and tomorrow it might be "Please choose a corpse to have dinner with." Seven strangers are trapped in this circular funeral home, each with their own secrets and skills: a physicist who can crack the rules, a sensitive person who can sense "abnormalities", an old man who was an embalmer... When they find that the last page of each manual has the same name written on it, the game begins to get out of hand. Lin Mo must find out the real funeral object behind the code before everyone is swallowed up by the "rules" - perhaps it is themselves.
