What do you do when you foresee disaster but no one believes it?
Architectural designer Chen Mo's daily life is precise down to the minute. Until that rainy night at the subway station, the image of the tunnel collapsing and the crowd screaming suddenly appeared in his mind - not an imagination, but a prediction as clear as memory. After pressing the emergency stop button at the last moment, he saves hundreds of people and exposes a secret he had hidden for seven years.
National Security Bureau agent Zhao Jianguo found him and revealed a chilling truth: Chen Mo was not born with any special talent, but was one of the experimental subjects of the "Prometheus Project" thirty years ago. A multinational technology organization, "Cronos", implants receivers in children's brains in an attempt to open the door to the perception of the time dimension. Most of the experimental subjects have disappeared in the long river of time, and Chen Mo is one of the few "successful" but anonymous survivors.
What's even scarier is that Cronus never stopped experimenting. They planned a terrorist attack on a shopping mall 48 hours later, not only to cause mass casualties, but also to collect the "time stamps" of the deceased's deathbed and to attract more potential prophets.
Chen Mo had no choice but to join the secret organization "Watchmen". But the real crisis comes from the person he cherishes most - his seven-year-old daughter Xiaoyu, who unexpectedly shows a more powerful and mysterious ability to perceive time than him. She can see the flow of time, talk to the past, and even touch the souls of those trapped in the moment of death.
When Cronus' pursuers are closing in, and when the countdown to a massacre targeting children begins, Chen Mo faces the cruelest choice!
