In the early hours of the morning in Guangzhou, a late-night radio station with over 100 million listeners became a broadcaster announcing serial deaths.
Popular female anchor Lin Xing received a mysterious call from someone claiming to be "Mr. Tomorrow" - accurately predicting the next murder 24 hours in advance.
Delivery workers, garage office workers, former colleagues... The deceased are all related to her without exception.
In order to save herself, she was forced to compete with the murderer in the live broadcast room: police surveillance, AI voiceprints, time rifts, and misplaced identities. The truth pointed to her best friend Xu Yao who "committed suicide" three years ago.
As the countdown approaches 00:00, Lin Xing discovers that the real butcher is not a human being, but a resurrected voice - a code for learning how to kill.
At the last second, she had to strangle herself in a live broadcast on the entire network to end the cycle.
Tomorrow, whose preview will she be?
