Lightless Day

A city with eternal daylight, the sun never sets, but it never illuminates the dark corners of people's hearts. Ten years ago, the astronomical phenomenon "Eternal Day" came. From then on, the city lost its night, and time seemed to be paused by an invisible hand. The police discovered an unknown corpse in the tenth year of "No Night". The heart of the corpse was implanted with a reversed pocket watch; the moment the pocket watch stopped beating, all the clocks in the city were reversed simultaneously. Interpol Gu Zhou took over the case, but it led to a huge whirlpool related to his missing brother, the underground organization judged to be the "Time Cult", and his own childhood amnesia. At the same time, three seemingly unrelated ordinary people - a night shift editor suffering from "daytime insomnia", a blind female fortune teller who can predict the death dates of others but cannot see her own future, and an old taxi driver who always lives in the memory of yesterday - successively receive backwards pocket watches anonymously sent to them. Every time the pocket watch jumps backwards, a layer of illusion peels off from reality: the dead speak, the living disappear out of thin air, and "tomorrow's self" appears in the surveillance video. When all clues point to the astronomical device behind "Eternal Day", Gu Zhou must make a choice before time completely collapses: let the city have night again and uncover all the truth; or let the day continue and bury the darkness forever - including himself.
