Li Shijie, CEO of a listed company, died in a car accident on the night of the winter solstice (December 22). The person who died with him was a middle-aged homeless man. The strange thing was that neither of them were wearing seat belts. At the same time as the car accident occurred, the company's board of directors held an emergency meeting in the absence of the CEO.
Lin Ruonan, the sister of CEO girlfriend Lin Ruoyu, returned from the winter vacation and led her sister on a journey of unraveling the mystery. The blue van that followed Li Shijie's car that night and eventually caused the car accident, the old watch from the 1990s that Li Shijie wore that night, the new expensive white down jacket worn by the homeless man, and the first mysterious phone call made by the truck driver after the car accident all surfaced one by one.
In the orphanage, the story of Li Shijie's wandering days and the story of the watch he used as a prop brought up incredible past events, especially the signing in the safe of the apartment where he lived, which shocked everyone.
Is the car accident an accident or a premeditated murder? What dangers will the sisters encounter during their investigative journey?
