In 2025, agent Liao Yong traveled back 22 years to investigate the "3.29 Time and Space Disappearance Case" in 2003. The case involves the mysterious organization "Era" and the Nazi biochemical conspiracy behind it. He must uncover the truth without changing history.
During the investigation, Liao Yong met Jiang Miaomiao, a 15-year-old genius girl. As the clues deepened, he discovered that "Era" was using time and space technology to conduct illegal experiments, and there was a fateful bond between himself and Jiang Miaomiao that spanned time and space.
This is an extreme pursuit of murder in the cracks of time and space. Liao Yong is not only Jiang Miaomiao's guardian, but also the lover she is waiting for in the future. In order to complete the mission, he must make a choice between salvation and sacrifice, and finally, as a "time and space ghost", complete the destined mission in the gaps of history - even if this means that he will completely disappear from her world.
