Criminal profiler Shen Xunguang, who is regarded as a "monster" because of his abilities, is forced to partner with Lu Chen, a decadent detective who carries a stigma. She can read the memory of death from the relics, at the cost of the darkness that devours herself; he is scarred by old cases and escapes the past in alcohol. When a series of murders all point to the unhealed pain three years ago, the murderer weaves a web of revenge in the dark. She probed the abyss for him, and he anchored the light for her. This is a fatal redemption that uses seven days of mystery to explore the truth and repair each other's broken souls.
