In the autumn of 1988, newspaper proofreader Zhou Mingyuan got a missing person notice from a scrapped printing press that would be published tomorrow. The missing person in the photo was actually his biological sister. At the same time, the serial disappearance case twelve years ago was reopened, and his father's old job proved to be key evidence. Every time the future is changed, another person will disappear for her; every time he saves a person, he will also lose a piece of memory. When all clues point to his father, Zhou Mingyuan must find out the real "revised" life before tomorrow comes.
