I {Su Qinghe} was the calmest forensic doctor in the city's forensic center, but I was injected with poison by my former colleague {Lin Mo} on the autopsy table and died out of hatred. When I opened my eyes again, I was reborn a week before my death, still holding the poison that caused my death in my hand. But something was wrong with this rebirth - I began to forget my memories frequently, saw a "past" that was not my own, and couldn't even hold the most familiar scalpel firmly. In order to uncover Lin Mo's conspiracy, I found a psychiatrist {Lu Shiyan}, but during his hypnotherapy, I discovered that another person seemed to "live" in my soul. Lin Mo's pressing step by step, the unfamiliar consciousness in his soul, and his constantly collapsing self-awareness. Is this rebirth of revenge a redemption, or a more terrifying trap?
