An explosion brought her back to five years ago.
An unsolved case tightly entangles two souls who should not have met.
When forensic doctor Qi Yan dissected a female corpse, he found that the metal marks in the body of the deceased were completely consistent with the unsolved "Qixi Festival Serial Murder Case" five years ago. However, a laboratory explosion accidentally brings her back to the beginning of the case - this time, she is determined to prevent the tragedy from happening again.
Criminal police captain Ji Chen is keen and stubborn. He never believed in supernatural phenomena until he met a woman who could accurately predict the details of the case. She claims to be from the future and knows the time of death of every victim, including... His own ending.
When the two teamed up to investigate, they discovered that there was a larger conspiracy hidden behind the case - the "Crescent Moon" organization screened women with specific genes through high-end clubs and carried out illegal organ removal on full moon nights. What's even more frightening is that the birthmark on Qi Yan's arm is exactly the same as the victim, and the truth about Ji Chen's father's death is also closely related to this organization.
Time is flowing backwards and the killer is evolving.
The only thing that remains unchanged is the gleaming crescent-shaped metal piece in the trachea of each corpse.
This time, can she change her destiny?
This time, can he break the reincarnation?
A hunt for a murderer across time and space, a forbidden love that grows under the shadow of death!
