I, {Lu Chen}, am a criminal police officer who has cracked many strange cases, but while investigating the "Shadow Serial Case", I witnessed my partner {Gu Ci} fall from a building, and I also died in a car accident. When I opened my eyes again, I went back to the 24 hours before the incident - it turned out that I was trapped in a "reincarnation of death". In order to find out the real murderer, I relied on backtracking to dismantle the clues, but I met the cold forensic doctor {Su Yan}, who seemed to know the secret of reincarnation and was related to the past of my family's destruction. As the investigation deepened, I discovered that Gu Ci had faked his death, and that he was darkened by old family grudges, and that there was a more dangerous conspiracy hidden behind Su Yan's mysterious identity. I chased the murderer repeatedly in reincarnation, and every time I got closer to the truth, I had to face cruel betrayal and life-and-death choices.
