An ordinary blind date draws the unremarkable Li Han into a trap laid by fate. Mist by the river, strange dreams, and a mysterious man drag her into the vortex of a parallel universe. She meets the gentle gentleman He An and thinks she has found a match made in heaven, only to be pushed into a sealed operating room after losing consciousness. He An intends to seize the parallel-universe administrator privileges within her, and a deadly conspiracy begins to unfold.
At the moment of crisis, sealed memories suddenly awaken: Li Han is only her surface identity. Her true self is Judge 002, a senior official at the headquarters of spacetime. She was demoted to a lower-level post for breaking the rules.
With her powers restored, 002 pursues He An with all her might, but in Universe B she witnesses the most devastating scene: He An has killed his own birth mother with his own hands. The dead woman, dressed in a blue qipao, is Li Han, whose identity 002 usurped and whom she betrayed. It hits 002 like a bolt of lightning. Only then does she realize that she herself was the one who drove Li Han into desperation and set the tragedy of matricide in motion.
Overwhelmed by endless guilt, 002 frantically activates a spacetime rewind in an attempt to save Li Han. But Li Han has already seen through her fate and willingly goes to her death, giving up her own life to keep He An alive. As spacetime collapses and the universe is destroyed, 002 discovers that she is only a copy of Li Han's consciousness, and that all her resistance has been trapped in a closed loop of fate. She defies the heavens and changes her fate by becoming a man, yet meets Li Han again and gives birth to He An, destined to kill his mother. A new cycle begins once more…
