Seven years ago, a 47-minute video was left behind at an ordinary graduation party. There were only eight people in the video from beginning to end, but it appeared many years later and seven years ago, a 47-minute video was left of an ordinary graduation party. There were only eight people in the video from beginning to end, but in a photo of the party that appeared many years later, nine people were clearly standing. What's even stranger is that the ninth person in the photo disappeared the day after the party, while the eight people present that night unanimously denied that he had ever been there.
Imaging analyst Cheng Yan was commissioned to re-investigate the matter. As old videos, photos, taxi records, chat records, and testimonies from that year were rediscovered, he discovered that none of the eight people seemed to be telling the complete truth.
Until he noticed a problem that everyone ignored——
If there are nine people in the photo, who clicked the shutter button at that time?
Perhaps there were never more than nine people who actually stayed in that room seven years ago.
