In this seemingly ordinary modern city, time does not flow evenly - some people can glimpse its cracks and even briefly control its trajectory. Lin Nuo, a former e-sports player who retired due to injury, is now just an inconspicuous courier. Until one rainy night, he witnessed a fight between extraordinary people in an alley, and his internal organs were shattered by the aftermath. When he was on the verge of death, his heart suddenly made a sound like gears grinding together, and time paused for three seconds, pulling him back from the edge of death.
The woman who rescued him calls herself the "Clockkeeper" and belongs to an organization that has been secreted for thousands of years. They guard the "Core of Time" that maintains the stability of the world. The "Clock Heart" accidentally awakened in Lin Nuo's body is the key to the Yongye Organization's frantic search. Faced with the strange ability of the members of Yong Ye to corrode time, the sudden solidification of space-time bubbles in the city, and the turbulent flow of time in the body that may backfire at any time, this young man who is accustomed to solving problems with the thinking of a courier has to learn to play with time in life and death crises.
When he discovered that his father's disappearance was related to the internal rebellion of the clock watchers, when teammate Mo Qingshuang's pocket watch began to rotate in reverse, and when the final plan called "Time Slot Zero" started counting down - Lin Nuo understood that the so-called reversal of time was never a rescue, but a gamble. This time, he wants to bet on "people" rather than "time".
