In 2135, "Yunding Apartment" in Xinhu City frequently experienced "missed calls from the future" incidents - residents mysteriously disappeared after receiving missed calls from their future numbers. "New Shanghai Times" investigative reporter Lin Zhixia persistently followed clues because her mother disappeared in the apartment 15 years ago. After moving into the apartment, she discovered that the disappearance was deeply connected to the inheritance competition of the wealthy Gu family in the apartment. She cooperated with Gu Zhaozhi, an illegitimate son of the Gu family and an apartment psychiatrist, and gradually uncovered the truth that Gu Mingxuan, the eldest son of the Gu family, used the intelligent system to create the illusion of "calls from the future" to cover up the murder in order to monopolize the inheritance. In the end, the murderer was brought to justice and his missing mother was found.
