This drama is adapted from the Douban Reading serial novel "Anemone", written by Beikebang. On the morning of the winter solstice, Yang Yuan's nine-year-old son disappeared in the stairwell. The police found that he had sneaked into the neighbor's house just before he disappeared. The suspicious neighbor has a solid alibi, as if he was controlling a magic trick of escaping the secret room by remote control. On the other side of the unit, Yuan Wu's father died suddenly after drinking. In order to embezzle his pension, Yuan Wu decided to hide his father's body in the rental house. During this period, he encountered the fear of hallucinations and reality, and inadvertently touched upon another mystery. Half a year ago, Lin Chuping, a single female white-collar worker who lived alone, woke up in her home and found that she had been violated while sleeping, but she had no clue about the murderer. There was only an ether handkerchief left on the windowsill... These seemingly unrelated people overlapped with each other in different time and space, and started again at this moment...
