Yintong Town is a small town hidden in the folds of the mountains. It is shrouded in mist all year round. It seems peaceful and peaceful, but in fact it is secretly weird. Lin Mo, a retired reporter, returns to take care of his seriously ill mother, only to find that this place is no longer what he remembered - the neighbor's aunt always greets the deserted alley in the evening, the eyes of his childhood friends hide the fear that does not belong to his peers, the clocks in the town will inexplicably turn back, and the sound of combing hair can always be heard from the old locust tree late at night. What's even weirder is that the people in the small town are very secretive about the word "yin pupil" and are accustomed to strange things happening, as if they are controlled by some kind of force. Lin Mo relied on his professional sensitivity to realize that behind these seemingly isolated and strange events, there was a secret clue that ran for ten years. The end of the clue was not only related to his mother's illness, but also involved the unknown taboos and sacrifices of the town. Those details that are ignored in daily life, when you look back and think about it, are all terrifying truths that send chills down your spine.
