There have been "returns of the missing" incidents in "Lingang" in Yucheng for three consecutive weeks: people who have been missing for many years will go home on their own in the early morning, but have no memory of the missing period, and disappear again seven days later.
When female reporter Gu Nanzhi investigated the first returnee, she discovered that all the returnees had received "trauma repair" treatment at the same psychological clinic, which had closed down after a fire five years ago.
As the investigation deepened, Gu Nanzhi received an anonymous recording. The voice was exactly the same as that of his deceased brother. The recording repeated one sentence: "Don't believe the fire in your memory."
On the night when the seventh returnee appeared, the entire city suffered a massive power outage. Gu Nanzhi found a still-running tape drive in the basement of an abandoned clinic. The "Experiment Number 07" recorded in it was her own name.
