Psychiatrist Shen Qinghe's fiancé Chen Yuan disappeared a week before their wedding, and the police determined that he committed suicide. A year later, while sorting out Chen Yuan's belongings, she discovered a recording pen hidden in the mezzanine of the floor. In the recording, Chen Yuan's voice trembled and said: "Qinghe, if something happens to me, go find a man named 'Old Ghost' at No. 47 Ping'an Lane..." The recording date was the day of his "suicide". Shen Qinghe decided to tear off this disguise, but found that he was being watched every step of the way. What's even more frightening is that as she gets closer to the truth, those childhood memories that should have been forgotten begin to wake up - it turns out that her encounter with Chen Yuan was never accidental.
